[quote user="Paul S"]Adrian, I wonder how you wound up with the never-mentioned FET 10? I prefer it to the EAR 834 I heard. Is this another case where it's full of old caps? I would not be at all surprised if futzing with those caps might yield as ...

I also use the Well Tempered Arm, but do not have the patience nor the urge to constantly fuss with the VTA setting. I set it for an average record and leave it alone. For me any degradation of sound quality is not so great and I just try...

Since I occasionally listen To K &K rakk dac unit and like it quite a bit I was looking at their phono stage for a long time. This phono stage is a little scaled down (in PSU) version of ART Audio Vinyl One unit which is very well regarded. Kevin...

True enough, Romy, and who knows, there might be a day or a late night when it sounds no different or even better with the wall power. Meantime, there is just no down side to using the battery for the iDAT-44+, despite my bad experience with th...

Rowuk, we do not disagree about the "battery/dynamics" equation. As you know, the "accepted notion" from the pundits is that "battery phono stages lack dynamics", and the one expensive unit I've heard did seem lethargic, albeit in a "salon". Howeve...

SOS, please note that your PP 2000 does not isolate one component from another within the reconstituted 60 Hz circuit. It only isolates those components from the noisy and variable wall voltage. Since you think you must isolate your TT and phono stag...

N-set, this might be a case where you can start with the 6E5P without working it so hard and still have enough gain , and correct as you go, because of the diminished frequency range requirements, and because of the third stage. Am I talking heresy ...

On any USA electrical wiring system, ALL circuits are referenced to and mechanically connected directly to a common ground at all times via the "neutral" wire, which ultimately connects to the grounded bus in the service box. And all UL electronics a...
|
|
Jarek, when you say disconnecting the phono ground from the PP ground stops the noise, why is it you don't just do that? Are we confusing "ground" and "neutral again? If the phono stage works quietly when its ground is disconnected, why don't you jus...

I'm trying to remember if you have copper water pipes, and wondering again how these measure for ground resistance. You MIGHT be able to ground your phono stage case to a water pipe as a "bleeder". You could start by "jumping" it, then do something m...

[quote user="twogoodears"]Maybe someone read this http://twogoodears.blogspot.com/2009/05/we-437-based-phono-stage-solid-rock-did.html, worth reconsidering its design - also (partially) using WE 437A - after the last posts discussion at Roman's.....

Hi,
I have a phono stage from the Korean company Silvaweld that uses the 5651 tube in the power supply as a voltage reference. It also is using a Russian 6C19Pi tube along with EF86 pentode as the high voltage regulator. The rectifier is...

Hi All, 103 or 103R + mass loaded SME headshell + 3012 or a 3009 + Seiki 1500 + hagerman opamp phono stage (good only with select parts and battery power) or an EAR 834 (with some mods) and some old Altec mic t...

I like to stress a point that the mammals that write thier doodles for audio publication are not juts ignorant fools but also the cheap, low class, falseificators. No wonder that the audio manufacturing companies do employ the so-called reviewers as ...

Fascinating info. My first post here though been a lurker for years. @Amir I assume the info you posted above about PSU changes come from Silvio? It's quite fascinating so if there's any further info published I'd appreciate a link to it.

How difficult is it to find 437As good enough for a phonostage? For commercial applications is it a dead tube. WE might produce it again when they stated to redo the tubes but the existence of the Russian 6C45P pretty mu...

Points about the self-sound of the PH-77 are well taken, not that I'll be spending 8K on anything any time soon, regardless of its "value".My own K&K phono stage is totally Spartan, just to avoid all the circuitry that typically facilitates the s...

Adrian, I wonder how you wound up with the never-mentioned FET 10? FWIW, it was one of the better all around phono stages I've heard, and - not that it matters - I prefer it to the EAR 834 I heard. Is this another case wher...

[quote user="Paul S"]Romy, I have noticed the same thing with the phono stage power supplies, that the big multi-chassis units with dual 100 lb. PS get no overall sonic advantage, all said and done. So how do we deal with the stupid, lousy AC that is...

Hello Romy,I am no power expert but here are my observations on your situation.Even though a PS Audio and others create a perfect AC sine wave this does not seem to be the answer, even for low draw front end components. It seems that some type of&nbs...

Great listening session today. Nothing too demanding, but some seminal jazz performances were included.Since the Telefunken tubes I was trying are well-used, I stuck in some 60s Amperex SQs, just to check for any possible changes.&nbs...

In a post at his K&K Forum, designer/builder Kevin Carter referred to this phono stage as a "listening tool", and I basically agree with that terse assessment.I think I have messed around with this unit enough now to get it "strategically".S...

I have been adding and reconfiguring gear recently and I will be needing a 6' digital cable very soon, when I add batteriy power, so I just went ahead and bought one of the "Synopsis" remainders Romy mentioned.This $5 discontinued Belkin blue ca...

I think I have had enough time with this phono stage now to make a few remarks about it. In keeping with the spirit of this website I am not recommending this component, just reporting on it.
I got my unit off AudioGon after keeping my eyes pe...

So far it appears that one needn't look to the TAP for any sort of sonic help. I have been breaking my own "one change at a time" rule by futzing with a new (K&K) phono stage as well as the CD/bypass stuff, and everything I do to/with ...

I am somewhat familiar with the dact: I used it in non controlled manner but familiar environment; it was assembled by someone else who also provided the necessary power supply; it was in two chassis about 15x15x~30 cm each (one for ps), so the equal...

It's hard to give prescriptions for ground problems, since they may be both myriad and complex. I can offer that my own current system performs best with all 3rd wire grounds disconnected from the wall socket at the component. For all I know, this ...

Last year I had the chance to listen to the Vitus SP-102 Phono Stage. When I remember right, it was ok, some of the better modern Phono Designs. It wasn't as thin and dead as Pass Phono for example, but it was also not able to go out of the way in re...
