OK, I have to ask (OT)...
Vance, do you mind posting about your bad AC solutions over on the Electricity thread?

Not that I'm desparate, or anything...


Best regards,
Paul S

PS: I think the Morray guy uses tinned copper strands.  OTOH, who even knows what's in the cheap-o Belken (and who cares)?

Romy,

I do appreciate the clarification on the site's philosophical approach. I will take it as constructive criticism. However, I do want to clarify that I only mentioned the Shunyata site because I *do* in fact think the information there is interesting. I would never expect anyone to be impressed by this...(although I certainly don't know why it would be offensive or considered a faux pas to reference it) it was strictly informational and certainly not meant to be any kind of "evidence" to prove a point....but I can certainly see that one could interpret it that way.
 
I will refrain from any such future references. My intention was merely to share my experience and some of what I'd read, for whatever it's worth or not worth. In my initial post, my intention was to tell people that the Bidat's sound might be even more appreciated with system enhancements such as power conditioning and, perhaps digital cabling if that turns out to be my final expereince. Anyway, thanks for the advice.

Bidat and electricity
Bidat, for whatever reason is remarkably sensitive to electricity, probably it is more sensitive than any other my priced of equipment. What however is ugly is that during different time, during the different problem with electricity the different methods to cure electricity had different impact to Bidat. Sometime sound dies and using a regenerator or balance isolator on Bidat it is possible slightly to reanimate the DAC. Another time no matter what you do it does not help – sure there is not known to me universal solution that does not crap sound and helps all time.

I have no idea why Bidat is so hipper sensitive to electricity. I thought to big up the PS caps and to put there instead 4kuF something like 60kuF -100kuF. I did not do it. Perhaps it would be worth to try…

BTW, my Bidat now entered the day 15 of the Nichicon Syndrome. Now the HF are done completely. It sounds like a gramophone with 5-7kHz max range. Taking about the good sounding digital…. Anyhow the HF should be back in 10-12 days..

I'm slow. What's your view on the moray james cable? Heard about it? Do you have a bidat? What digitial cable have you found to work best with it.

Romy,


Very interesting. I agree that the Bidat is sensitive to electricity. BTW, you should know that I run my Bidat directly into my Classe Delta 2200 amp via balanced interconnects. My use of the "digital volume control" may color my impressions of the unit. I assume you run yours through a preamp.

BidaWright 2010?
fiogf49gjkf0d

Form email I got from John Wright

“PS, In case you care, the Bidat gets better all the time with fresh updates ….I mean it will sound broken in comparison. I have made some very good changes to the power supply and the output stage that have made it more transparent and with real bass now.  It's even more musical.  And no, I didn't just change the op-amps and caps.  I made some actual circuit changes and further simplified things.”

That is tempting and I would probably go for it. Bidat does have own unique sound that woks in my view remarkably well with very aggressive had-reading CEC TL0. Having Pacific and Lavry Gold I still have Bidat paired with TL0 and frankly no motivation to change anything. The lowest bass was always Bidat’s weakest point and if John found a way to get more or it then it might be very good. Did anybody exposed recently own Bidat to the most resent modification and can corroborate on John comments?

He has mine now.  Of course, I don't give a crap about the "power supply", since I am happy with the battery.  And it's hard to imagine anything on my VERY basic unit getting further "simplified"; but bass is nice.  We'll see.

From an email I just got from the site’s visitor:

"I got my bidat re-modded by John about three months ago and a friend of mine had his done last month. We are both pleased with the changes. Mine already had the super mod package and his had no previous mods. The latest mods strike me as more "analogue." Break in continues to be lengthy for John's mods. The unit didn't settle until about 150 hours. During that time, it was very disconcerting. Some recordings sounded like they'd been "re-mixed." Fortunately, everything returned to normal but with improvements in bass (more tautness and more extension), less digital harshness and an even wider and deeper soundstage...."

2010 Bidat Modifications: Cat becomes a Guinea Pig
fiogf49gjkf0d

Spoke with John last night. It seems that the comments of the folks who did the modifications recently are not relevant and the new 2010 modification were not yet implemented on any DACs out there. The new modifications are mostly in PS and analog stage, not the parts swapping but actually circuit change. John very positively commented about his new changes. It is hard to say. We never met him and we never were listening the same sound and correlate our notes after all. From different perspective 3 modifications that John did on my Bidat over the year never took me to the direction that I did not like. So, I decided to try and to see what would happen - the Bidat will riding to Canada next week…

I have a very good grip what Bidat does in my playback as it runs parallel to Lavry Gold and I know very precise what the difference is. It would be very interesting what the Bidat 2010 would do. If John will be able to get out of Bidat the same quality of bass that Lavry Gold has then it will be fantastic.  Let see how it goes….

Bidat back before move?
fiogf49gjkf0d
Romy
 Do you think the Bidat will be back before the move for impressions on the mods? It might be hard to tell what/if the mods make a difference in a positive directions if you throw a whole new room into it. Your experimental control group will be dismantled. If it hasn't gone yet it might be wise to hold off on the mods until you get a thorough idea what your current Bidat does in new room. That is if you think the Bidat won't be back before the move and you don't have a second Bidat that sounds identical to the one you want to send to John.

I wish I was as confident about the moving as I sound. Anyhow, if I get the house (there are some kinks) then I won’t’ get the Bidat back before I move. In fact, John was complaining that he was busy and I explicitly asked him to keep it for a while – so, the Bidat might be back to too soon. I do not care about the recognition of difference before and after. I know very well how Bidat sound. I also have my transport running two outputs (Bidat and Lavry Gold) and the difference between them is very demonstrable and provable. So, whatever sound I will end up in the new place I will always have Lavry Gold as comparative reference. So, I am very confident that I will be able to identify the Bidat’s before and after.

The last Bidat Upgrade - above 140Hz
fiogf49gjkf0d
While I was moving in to my new home John Wight undertook my Bidat for his new update.  Up to now I did not have playback properly performing but the last 2-3 weeks I feel that my playback is back. Again, whatever I lien now has only upperbass horn at the bottom and there is nothing under 140Hz .

So, I give some listening to the New Bidat. It is very easy for me to judge about performance of Bidat as it sits in system in with two other DACs and I know with very high degree of precision the sonic delta between all my DACs.

As it appears to me the updated Bidat has no sonic difference between Bidat before and Bidat after as all deltas that I expected was there. At least it I my observation above 140Hz. This is a good sign so far as I was afraid that the changes might impact Bidat’s upper range, something that I have absolutely no problems with. I can’t wait to try Bidat a full-range.

The interesting past in this story that Bidat this time came with own set of digital and analog cables. That will be a separate dedicated subject when I have a full-range playback back.

Bidat with new midbass and proper performing purepower
fiogf49gjkf0d
Romy,
 My Bidat being extremely sensitive to incoming electricity and now with Purepower in my mix I am getting to know my Bidat in a new light. I did think I had a grasp of what the Bidat could and couldn't do but feeding it through Purepower it has grown on it's previous strengths but added others. The space and imaging that is it's hallmarks are greatly expanded. A little confusion and smearing in complex passages is completely gone now. All sounds tangent independently now and can be followed as such but also in bigger space. It is wonderfull. It was my secondary dac for awhile but not anymore.

 Now that your midbass horns are dialed in and the electricity is back for you like pre-move days have you any observations on sub 140hz performance of your Bidat since latest power supply modifications by John? Does it approach the Lavry bass in particular? Do you still confirm that above 140hz it is still as was since your electricity is sorted now?

Bidat always was supper sensitive to electricity. I had an army of small power devises before I used PP2000 and used those small devises to a different degree of success with Bidat. The front end is usually is more sensitive to electricity then power amps.

As I said above, the last update did not do much in term of sound and the same difference that I remember Bidat had with Lavry I feel that same difference persists now. Electricity or midbass horns have nothing to do with it.

Bidat and bit depth
fiogf49gjkf0d
Romy,
 You have mentioned somewhere in the Bidat-Lavry thread about the Bidat being a 20 bit dac but throws out 4 bits (quote below). But, you have also stated that you play 20/44.1 files from your pc set-up into the Bidat and more specifically to compare the Lavry and Bidat. I am now into recording files at higher rates and bit depth but will keep second copies to play through the Bidat. I'm specifically taking 24/96 and resampling to 20/48 which the Bidat plays fine. Can I ask where or how you came upon this info about the Bidat tossing the 4 bits internally?

"Among the disadvantages I would name /

2) 20 Bit and 44 kHz maximum. It reads 20 bit but it toss the 4 bit internally and in reality it posses 16Bit."

Miab, first of all it was not “posses” but “process”, I need to add it to the list of my epistolary treasures. Bidat uses 16Bit chips inside, so it is not the question what it process (it will not process more than 16 bit) but what it will be able to lock. Bidat use TDA1547 that is 20 bit chip but from what I recall the conversations with people who know how Bidat works they expanded to me that it has only 16 bit useful. Then I was informed that many 16 DAC in past in reality were 12-14 bit DACs…. The stream acquisition part of DAC is a different thing – it is about what kind stream DAC can read, not process but to read, or to lock. Bidat lock 18 and 20 bit just fine. I never tried 48kHz feed and I am VERY surprised that you report that Bidat read it. To the best of my knowledge Bidat has no 48K clock, how the hell it read it? Well, it might have VERY wide window bandwidth for locking and it might lock your 48K stream with 44K clock but you will have music played slower then it intend to be. Try to play 88K with 44K clock - you will see the effect.

Bits and my wits
fiogf49gjkf0d
Yes the Bidat does lock 48khz very well and so does the Idat-m. Something even more suprising and coming from someone that knows these dacs very well is that on a few samples of Bidat they even lock at 96khz! Alas I am not so lucky. Mine is 44.1 and 48 only. I downsamle 88.2 to 44.1 and 96 to 48 for simplicity of computer processing and the elimination of any potential issue's. 
 
About bits. The datasheet for TDA1547 clearly states 108db of dynamic range for this chip which would be in line with a 18 bit dac. A 20 bit dac should in theory be capable of 120db. I'm not sure what to make of this. I have played the same tracks at both 16 bit and 20 bit and at this time I believe the 20 bit to have the slightest of advantages. I must admit that I might not be able to tell in blind testing at this point. 48khz vs 44.1khz is easy to tell though.

Miab, Bidat specification said that it is 16 to 20 bit input.

…but the last 4 bit of 20Bit signal will not be processed. I did research that subject in past myself and asked a few different people. I do not remember already who explained it to me, it might be John Write. You are in Canada, get in tosh with him and he can shade more light for you - ff Bidat has true 18Bit chip then it very much might toss out  not 4 upper bits out 20 bit stream as I said above but 2 bits. BTW, I do not recognize 18bit – it does not make sense to me. If you are in CD-compatible world then you at 16 bit and this is your threshold. If you jump out of the CD would and right-read uncompressed PCM files then why would you limit yourself with 18 or 20 bit – you for sure would go for full 24 bit. Well, there is no such a thing as true 24 bit or cause but why not to use the max bit depth is available? 

Also, as I said – I am very surprised that Bidat reads 48K. I was trying to feed Bidat with 88K and it does not like it. Bidat shall recognize the sampling rate in the incoming stream and PLL own clock to source. Usually the phase-locked loops in DACss are very narrow and this is why most of the DACs that do 44X and 48X has in fact two different clocks. Does Bidat has such a wide PLL window that is tune itself to 48K? That would be funny but since you report it I guess it is funny.

DPA dac

Dear Romy,Though not related to this topic much, but I want to know your opinion about discontinued DPA dacs. There is a chance for me to buya PDA 1024. For the moment I dont have a proper transport to test it and just use my digital radio's output. Thanks in advance for anycomment.
Regards,Armen

Cheap DVD player
fiogf49gjkf0d
Don't you have one which you could  use  as a transport to asses your DPA dac and make up your mind for yourself? (it may happen that you'll like cheap DVD player better sounding by itself) 90% of cretins who own Bidat do it only because  Romy prizes it,  in hope that some day they discover the reasons why he likes it so much. Not to mention that it suddenly became a good investment and a dac of this vintage instead $200-300 goes for $2k+
