[quote user="Paul S"] http://app.audiogon.com/listings/omnigon-full-function-tube-preamplifier-phonostageLooks like a serious effort that has been kicking around for a while.What tubes are used? Are they twin triode, like 12AX7 or - more likely - 692...

Hello,May I have your comment for my diy LCR phono sound. Thanks.http://www.youtube.com/watch?v=gwO6Uc-oOqg Bee Gees Greatest (3 songs)http://www.youtube.com/watch?v=ZYjRayM78FM We Are The Worldhttp://www.youtube.com/watch?v=W9Jvvockz38 The Beatl...

For some time I have felt that most audiophile phono stages are over-built, especially those pretending to be thought-out, "no-compromise" designs. Ironically, it seems to me that few (or none) of the "thought-out" designs I have seen and/or heard a...

Perrew,
LCR is not active at all; it is the very same passive EQ as your RC? I think you a bit confused with terminology. The main logical explanation (there are many of them) is that capacitive filtration is very bad one and need to be minimi...

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... also worth remembering that ...

SOS, as a starting point, it does not seem at all odd to me that adding an "other" piece of equipment to the electrical chain might require a reconfiguration of the system ground scheme. Of course, the phono stage is the worst case for hum, PP o...

I finally got a PP unit. It is 1500W model as this is enough for now. It is the actual Golden version (Plus not available anymore) but the PP factory claims it's identical electrically just in a new aluminium case and some extras added. I managed...

Metal caps over phono stage unused RCA jacks can help with stray EMF/RFI. Cardas and others sell them.Not saying something is wrong with the PP, just saying it doesn't take much to get noise from a phono stage, including any change in ground potentia...

Since the 2007-2008 alchemic music season and consequentially live FM season was over (the event I marked with my “End of the live Phonostage”) I have been spinning a lot of vinyl lately. So, I spent some time with different phono cables with my diff...

[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 used to think that DG had some pretty awful recordings too - and they did, but the pitch related things seem to have more to do with them not using the RIAA curve. A bit of HF tweaking brought back the balance - if the system was capable! My bigges...

application far more sensitive than simple line linestage and in addition to that ,that pre is percived to be colored and syrupy tick. Are you trying to cover up that harsh and cruel sound you're talking about ;) Could you kindly explain why pe...

Thank you for the feedback guys!
- Bill and drdna below is the actual physical situation. The distance to the Decca is 110cm, to Phono 140cm (the noise is present even if I switch to a shorted MM input and the PP is on batteries...

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...

Has anyone had the opportunity to listen to this device and form any impressions?http://www.sound-smith.com/cartridges/sg.htmlI recall that Win Labs made something similar in the late 70's but I never heard one....

Hi, I am new here and would like to say hi.I am a owner of an ET SU-1 and would like to know what phono stage would go best with it. Would a Lamm LP2 be a good match?Will be using a Dynavector XV1s with it. Thanks in advance...

Referring to the threads a few month back:
http://www.romythecat.com/Forums/ShowPost.aspx?PostID=4937
I wonder if I need to play with the coupling cap between the first and second stage. Now I have my beloved ElectrocuCube 950. In my former version...

Since my “End of Life" Phonostage have materialized I got exposed to a temptation of finding a “right” cable between my tonearm to the phonostage. The most critical cable between the step-up transformer and phonostage does not exist in my system anym...

Rooting around for manufacturers' operating curve/info on 6922s I came across a short paper I got years ago from electronics genius Roger A. Modjeski. In a nutshell, RM talked about internal variables in tubes that affect their electrical charac...

Romy, why not get this guy's phono stage to try so we all can benefit from an unbiased opinion of its performance? Rgs,montepilot...

Yes, Roman: the two stages design is having the gain you correctly pointed-out.Sure would have paid - and it was discussed, as well, during pre-building weeks - to go for an higher gain design, BUT I feel more confortable in going ahead to play with ...

Hello Paul,The first stage is a pentode, so the Miller cap is negligible. As for the other things you mentioned, there is a detailed exploration, which covers some of your points, by Dave Slagle at:http://www.intactaudio.com/forum/viewtopic.php?t=102...

An interesting devise, They allow to adjust the midle point of the RIAA curve. I never have seen it and I wonder why would it be necessary or desierable?

Way back when I was an undergraduate, we studied about baby ducklings that some maniac made to follow a "surrogate mother" around a moving turntable. To make a horrifying story short, the "study" concluded that the harder the ducklings were made to ...

There is a new company out there that make some electronics. I do not know them, never heard anything that they do and do not know anyone who use their products. They have a phonostage that might be interesting.

The positive feedback published a review by Marshall Nack of SP-102 Phono Stage: http://www.positive-feedback.com/Issue69/vitus_sp102.htmIt is an interesting review despite that some of the Marshall’s comments do not makes sense at all. I did not he...

Hello Romy
Looks like you may be about to set us off salvaging smoke alarms (like that boy scout a few years back) ;o)
An idea that I haven't seen explored yet for low level stages is the use of Peltier Effect heat pumps to cool the valves. As ...
