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...

it might be tricky for this (as it is) to work well as a phono stage! It also seems rather involved for a line stage too. (too much gain?) The chassis does look substantial though. Presumably the valves are pcb mounted inside? What will y...

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...

I have a PDF file of the manual if it interests you to read it, I can email it to you.
The unit weighs 80lbs, uses 6 6sn7's.
What I found a little odd was the spec for the phono is it says : MM Phono Stage Gain: 64 dB at 1 kHz
I own a Expre...

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.

What they say:Every audiophile music lover knows of the legendary sound of Koetsu phono cartridges from decades past. Those old enough to have experienced Sugano's Koetsus retain the memory of a musical experience unequaled. Few were privilegedd to o...

1) GND NOISE
After more experiments, I can proclaim a victory over the 100Hz noise on my End of life phono. For whatever reason the GND connection does not want to run in a close physical proximity of the line and n...

There is more information about the Lamm new LP1 phono preamplifier, including the price of $33K

The images do charley show two step up transformers at the ent...

Yep, I fixed it. If does sound very good now, exactly how it has to be. It turns out that my suspicion were correct: my Micro’s fat cable has died on me. I absolutely assure you that no one would believe that a regular phono cable able to introd...

I run both of my Reference and Daily tonearms into my “End of Life Phonostage”. As I told I do not know any way to commutate signals at phono level signal and I just re-plug the phono cables at the phonostage’s input. I have no problem with that ...

[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 ...

Jarek, because the PP introduces different grounding schema into your system I did suggest earlier that the phono may require alteration to suit. In my case, when the grounding schema was altered, one phono had a similar issue to yours and the s...

Romy, I am aware of your well-reasoned prejudice against audiophile/boutique parts, and I agree that they are by-and-large the first recourse and last refuge of Morons.I thought I'd chronicled this phono stage stuff so far, but obviously not in ...

I have posted about some of my recent experience with longer "naked" HF ribbons in Romy's "Water Drop" thread. Here are some observations that relate these drivers back to the ML2s, along with some other recent ML2 trivia.My speakers are listed...

Looks like I've found a solution but I don't understand it:
1) Lifting the phono ground from the PP with a cheater plug and connecting the phono case to the SAME PP ground with a separate cable not only does not bri...

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...

i do it and i did it, but as a newcomer you have to sort out all the infos...not that easy!
[quote user="Romy the Cat"](This is normal, I have written about it many times. Those large bass drivers have a lot of inductance in Voice Coil, the inductan...

N-set, I've never tried to make a "silver path". I have thought about Ag arm wire but I have not tried it. My cartridge coil and tonearm both use "high-purity" Cu wire, and the Cu arm wire feeds directly to the Ag wound SUT, which I use not because...

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...

I'm a phono moron, but having had several phono preamps, I think I can understand what finds Romy right in the EAR 834P, which I love. I'm not as skilled and crazy as to try to make all the Thorsten mods in it by myself, but I've tried some tube swap...

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 ...

Over 10 year later, I finally "finished" and installed a shielded version of the above cable for the short run between my phono SUT and my phono stage, replacing the nondescript Placette cables I've been using there all this time. As anyone experien...

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...

I think there is a definate trend here regarding distortions that cannot be ignored. Guy, you pointed out some excessive 2nd order harmonics with the Melq bias point. Hey, maybe so. I haven't really looked into this tube - but I jus...

I am sorry that Steve is unhappy with the inability of PurePower tech support to resolve his phono hum. It is not because we did not provide adequate support. We brought the unit back to our plant and gave it as thorough a series of QC tests as possi...

Something fun to think about is that the length of this sort of cable can change the sound, due to internal "reflections", this sort of thing. I've read a lot about it, as it affects the "communications industry", and laboratories, and it gives me he...

[quote user="guy sergeant"]Some of it, (the current speakers and some of the amplifiers) are in my view, not outstanding. Other items, (the big preamp, phono stage, cartridge, MC transformer, silver cables and largest power amps are exceptionally goo...

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...

[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.....

Paul,The gain of my phono stage has the RIAA loss factored in. Without the RIAA loss counted, the gain would be about 66-68 dB. [quote user="Paul S"]I have never used the 417 or 437, but I have heard plenty of whining from folks who do. They often p...
