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...

Nice minimal construction, Romy.How do you keep the pots from drifting?Have you thought of using small batteries for the filaments? I have not tried it yet myself, but it is the next thing on my list; dead simple and dead quiet, if yo...

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...

[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 ...

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 ...

Hi!
Stefano just made me aware about this forum, so I registered. Interesting thread about LCR RIAAs, one of my favorite topics :-)
About the gain of the WE437 phono: Since Stefano wants to use external MC step ups, I designed the phon...

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 ...

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...

N-set, you will never know how your phono stage sounds with the "silver path" until you try it. FYI, the WBT Next-Gen M/F work well --- with each other, but less well, mechanically, with the Vampire sockets; I don't know why yet. The Vampire seem t...

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...

|
...future subjunctive...Romy, I am not sure that the first part of your response actually addresses the first part of what I was talking about. So, I +/- repeat myself:As an extreme example, if I see a claim of "80 dB gain" for a phono stage, it is ...

The 'Death' phono stage. I like it, it may have legs!...
|
|
[quote user="Paul Costa"]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 kH...

No matter how often I go through it I still frequently get confused and disoriented when tubes go bad. In this case I have been integrating a new (passive) pre-amp and a new (tubed) phono stage into the system, including trying various tub...

Hi Romy,
I did the review on the AcousticPlan amp, called the "Santor". It is indeed a two-stage amp using 4 6922 tubes in parallel to drive a high Bias Mosfet output stage (it is class A to approximately 15 watts and runs very hot). It ...

Correction: The CH brand phono stage I looked at is (of course) a current amplifier, and no reason to be curious about a regular old, typical voltage amplifier. I see there is also a VERY Expensive, 4-chassis version of this (already expensive) pho...

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...

Again, there is no need, even for "safety", to have a separate ground wire if everything is star grounded. Since the neutral and the safety ground connect at the service bus, running the "safety ground" back to that bus for your phono stage apparentl...

I have no idea who Panagiotis Karavitis is. He isist that he is doctor and I hope he is better doctor then an audio reviewers, if not then I hope he cure only republicans…. Honestly I did not read the Karavitis’ review in while. I did first paragraph...

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 too often...

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 painted myself into a corner with only one tonearm and one cartridge, and my one cartridge has gone to the Ortofon Spa in DK, I am sans phono until my cartridge returns. This means I have too much time to think about a phono stage, as oppose...

Well, Romy, it took me a while but I finally got the cobwebs cleared out of the phono stage, and the Shostakovich 10th was totally engaging as music (via the TAP). The recording is the (late 60s) Melodiya (stereo) with Yevgeny Svetlanov/USSR Syp...

After years of using the Expressive Technologies SU-1 and SU-2 step up transformers I come across to a fact this morning that the Expressive was reviewed by Robert Harley in June, 1992. I read the Expressive’s preamp review but I never seen this one....
