All that has been discussed at length many times this board. It seems that people continue to confuse neutral and ground, and I agree that it is confusing. Basically, any commercial "power company" power grid supply in the US will be grounded at a se...

N-set, it is difficult to say anything without seeing the circuit. I think that you did not exactly my version but made some modifications; I do not know/remember what they were. The major think that I see at your picture is that your main grounding...

Thank for the link. I did not see it is it does look interesting. II like those crazy, unreasonably-obnoxious, no hold barred projects and they usually do push the envelope of what is possible. I did not have a chance to read the whole thread. We hav...

Paul, thanks again for a nice input--sounds for me indeed seductive (well, I'm anyway +/- "self-convinced" to give a silver/amo a try).Do you use silver wire also in the tonearm? What I have in mind is a 2nd, all silver path for the 834, which would ...

A few days ago I had a discussion with an audio guy I know when we were trying to name audio things that would be "nice" to be done in audio. For sure the industry fools are trying to convince everyone and themselves that the audio "nirvana" is jus...

A few days ago, enjoy the music side published an article about future of audio, run the author was trying to predict what will be this guy and other in future. I read just two paragraphs at do not read anymore as I am not interested in the persp...

There is another very good article with the simple resistors conversion network.

Still, I would like to make it “kosher” and have ordered the double adaptor with a transformer from RedCo:

I never thought that it is so painful: to have a playback and no front-end thatcan drive my amps. Thankfully the Placette is coming back now with the whole 12 channels and the tape loop. I have some ideas how to chance the connections across the who...

As with everything audio, one has to put it in context in order to evaluate it. In my case, the ML2s have a reasonably "high" and stable input impedance, the TAP TVC has a reasonably low (and totally stable) output impdance, and my cable runs are sh...

Ok the Macondo is all done in new room, including the bass channel. I am uploading the calibration check sheet not as much for you but rather for me. I have been keeping it got years and constantly am loosing it, now I will know where to find it. BTW...

[quote user="The Cat"]Nope, I had it floated and grounded and practically have seen no difference[/quote]Yes, I would suspect this in most installations. I guess my concern is for the rare and unusual. A floating speaker might be able to ...

[quote user="Romy the Cat"]I do have two cables RevB that are dried out and that need to do refilled but I afraid to send it to Purist and they might lose the Right sound. Purist use nowadays a new liquid and go figure if that liquid make the cable t...

Hi Paul,WTF is probably the right question. The time has been the problem - in the past 2,5yrs Ive set up my own audio company and only recently came back to working on the front end of my system.I changed the concept and bought the FR64S arm togethe...

Ideally, you'd want to drive 35 feet of balanced interconnect with the low impedance source ( say below 150 ohms or so). How low depends upon interconnect capacitance. You can try Jensen output transformer to convert SE to Balanced at the phono-stage...

Here are my notes on adapters. I am not an engineer so I do not have further explanations readily available but could probably dig them out.1) It is physically impossible to make an RCA male or female with an impedance of 75 Ohms, so all digital RCA ...

I was so glad to stumble on to this site. It's amazing!I've been a Bidat owner since 1995 and I had the latest mods done by John Wright a year ago. Romy, it takes several months for those blackgate caps to fully calm down, but you are in for a t...

[quote user="Romy the Cat"]Well, Nicanor, I very much disagree that room acoustic being basically invisible to us. People who deal with sound more or less intelligent always not only pay attention to room acoustic but recognize sound ONLY in context ...

You are correct, the idea is to "hard tie" the tubes together (otherwise you don't get the rigidity... think of a paintbrush where the paint has dried in the bristles... this is what you want). You would need small welds between each tube... a 1 inch...

I woke up this morning to have the brightest thought that my DHT issues are probably caused by how I have wired up the filament transformers. When I ordered all the transformers for this project I gave Lucas of Black Art Automation the design brief ...

Romy, I probably have it wrong, but this "negative impedance" scheme sounds a lot like "Servo". If it's anything like this, then no, i have never seen this applied to mid-bass, but only to "subs". But how would a very small tube amp "control" a mot...

Yeah, so the closeness of the grids results in a higher current gain. So what? What is the relationship between gain and sonics? Are you saying that all high gm tubes sound better than low gm tubes? And does that include 300B ...

Hi Anthony Agree, waste is waste. The bigger the better. If you care bout sound too, i recommend the RG213 radio cable. Its perfect for that purpose. First, its coaxial which eliminates the inductance. Second its very hard so that during vibration th...

[quote user="manisandher"] But can't you simply take the tape out from your Placette and plug it into the Pacific's analog inputs? I'm assuming that the Placette has, in addition to its variable output, a fixed output...[/quote] Yes, I have thought...

Hmmm, this is interesting. Is it your opinion then that if someone but Dominus on a cable cooker it could be ruined? This would affect trying 1990's Rev. A & B in my system because they can only come from used market and it would be unknown how they ...

[quote user="be"]I recognise your observations about the Ag vs. Cu sound, but instead of mixing the two materials I think it is better to change the diameter.I experienced 0.5 mm silver wire to be too thin soundvice, have you tried 1.0 mm or even mor...

Thank you for the description. How they are sealed is what I am most curious about. I've tried a few different techniques to seal fluid in the tubes during my cable experiments. Does it look like they simply injected a clear silicone, terminated to R...
