In this cable thread there are some ideas about materials and construction of cables. My most recent attempt for good-sounding shielded phono cables are from Bud Purvine, using his specialty Litz wire construction, Vampire 800C connectors, and unblea...

Big differences between PS in my giant amps and my DAC, my passive attenuator and my phono stage, TT. PS has to be "good enough" for the application. Maybe "reverse engineered" from the demands end requirements (ie, the mind of the listener). Throw t...

How ironic that I finally got my phono running through the ML2s, and just as you say, it was not all it should be. In fact, I would have to say at this point that I am getting better sound from my crappy CD player, which I u...

Did you just answer your own question? Use the B2, then. Plenty of nice, small tube amps for tweeters, if that's what you want. I could list tube and SS amps, but I hate doing that "in public", not to mention, as you just pointed out, you only need t...

I think that any line level tube stage can be every much of an expressive tool as any other device in the chain. I am also not sure that the biggest difference between digital and analog is the sampling process.How "transparent" is a cutting lathe or...

Good picture .I don't know why but it reminds me a tonal balance of old movies, maybe because of the subject.
As to the phono stage, Erno Borbely has a J-fet (discrete op-amp) based unit -quiet and MC capable.Use google. It is a kit but I'm sure yo...

Hi Romy, I don't doubt for a moment that there are plenty of people 'who know' who will wax lyrical about the benefits of open loop eq in feedback circuits. There are people 'who know' who will tell me that valve amplifiers cannot be as good as trans...

Hi Guy, [quote user="guy sergeant"]My experience with the 834p stemmed from having one at home for about a year soon after it was launched. I did try different types of ECC83 in it which did change it's balance slightly but not enough to make me like...

Hey Mr M, phono stage will be quite a while yet. I'm way behind on my commissions for various unfortunate reasons :(
Did I tell you I got my own cool Dragon Stockholm vinyl?
Um, probably...

I must say that I have always thought the Cardas "Golden Ratio" schtick was pretty lame. So it was with no small measure of trepidation that I sent off a rather outlandish sum of money for two Cardas Golden Whatever 4.7 uF caps for th...

I am with you on this one. I am also very suspicious of gigantic, 4-chassis phono stages if only because I just wonder why the need for all those damn noisy parts, along with concommitment connections?So it really pisses me off to admit that th...

Vinyl almost died after the launch of CDs, but today the popularity of vinyl playback is on the rise. Music stores are selling more music available on LPs, and many audiogon systems include turntables. So where are the full-function preamps? Before d...

Romy Hi, there is nothing to say really, I was trudging up the usual hifi route, ( B&W 800's usual high powered solid state amps ) I thought a turntable upgrade would be the last step! Went to GT Audio to listen to Thomas Woschnicks tur...

You might think I'd learn by now, but over the last two days I have traced sonic problems to the following: Dirty pins on one of the tubes in my phono stage; Loose counterweight set screw/too-heavy VTF; Loose cartridge mounting screw/...

[quote user="Paul S"]I thought of the AMR equalization curve options as I listened to a London FFRR LP (Kubelik/VPO/New World) today using my new technique to optimize stylus tracking.The FFRRs are well known to have some extra LF, all right, but wit...

First of all, thanks for additional detail. As mentioned I can speak only for my Fidelity Research XF-1 (30dB). Loading it on secondary as you mentioned, it ALSO damps the trannie - result in my case: less resolution. Primary loading is MUCH more sen...

Romy,
New member around here great website! I have what is probably a silly question about the above EAR schematic. I've been in the planning stages of scratch building a phono stage and have been looking at a few designs and ju...
|

I'm not sure why my DAC cut out, other than it's a short. Meanwhile, I am listening exclusively to vinyl, as opposed to mostly vinyl. I sure wish I had FM, but no sense worrying about that in these parts, not to mention all the records I'...

Needless to say, my arm (the Well Tempered Reference) is all about silicone. And indeed, damping does change - somewhat - with the temperature. However, it takes extreme temperature changes to make me feel the need to adjust damping (whic...

This is always good advice, to get to know the character of the phono stage. Because my favorite cartridges are not low voltage (I use Decca London Jubilee and Reference) I have never had a need for the ET SU-1 step up unit. In fact, I had this in my...

Well, that sounds perfectly reasonable, and it also gives you an out in case you happen to hear something else that really turns your head.Although 2007 did not make it appear so, I have had +/- the same thoughts about gear for some time, perhap...

Hello Romy
This is my first post. Did you take courses in electronics and mechanical engineering or have you learned yourself outside of a structured environment? I am very interested to become proficient in working on/modifying my own electronics. ...

Sorry, Adrian, I did not hear either phono stage in my present system, nor did I A/B them, but I "compared" them in my "aural memory", with the actual listening sessions spaced several years apart. Back around the time of the FET 10, maybe a li...
|

I would not say the circuit (per se) was becoming more sensitive to tube choice (and neither would I claim it's not...); I would say that as I have developed the system I have been better and better able to hear what more and more piec...

Romy's virtual example is a wonderful example of "context", perhaps the only error up to now in this thread.The description of Walters VirtualPhonoStage would be a great article for the website: http://www.I_am_a_deaf_musician_but_so_what.org, but ha...

Hi Romy,The thing is.. Mr Schroeder is making a living and as such (being someone who needs to make a living in order to pay for stuff), he may from time to time have to associate himself with people that will facilitate this ability to help him pay ...

If you can do it, try isolating both cases/chasses from your "ground plane(s)". Use one inclusive "ground plane" for both the PS and the gain/RIAA sections, and ground this "ground plane" to the house "neutral" wire. Do NOT connect any shielding to t...

I've spent two more nights examining and fighting my ham (I'm vegetarian and I want my phono to be so as well).1) I did Romy's excercise with shorting the stages via a 0.47u cap to GND. Shorting the plate of V2/grid of V3 resultedin the biggest reduc...
