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...

[quote user="Paul S"]Is the "ground plane" in this case literally a sheet of copper that you run all the grounds to? If so, this may be overkill on the one hand and an antenna/noise magnet/generator on the other hand, and/or it may well make for grou...

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...

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="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...

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="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...

In impatient, ill-advised. manic efforts to "compensate" for the EFFECTS of bad power I have swapped ICs, used different output taps, re-configured grounds, swapped tubes, re-positioned speakers, adjusted VTA, messed with my BR ports. And ...

It has been 1 year since I started working with the ML2s with all new tubes installed. The ML2s have been, by far, the biggest step I have taken in hi-fi in 45 years, and the "upgrades" I have done since the ML2s have necessarily been in a...
|
|
As I play the old-but-new-to-me ML2s more, and as I slowly replace tubes, performance has changed a lot, and all for the better. Understand that I am not really talking about the ML2s, but about the sound I am getting, which is so different and...

Romy, do you power your End of Life phono from the PP??
I have the same phono, with choke input PS for both the heating and the HV.
1) If I plug the phono just to the wall, the noise just normal wi...

What kind of di-el grease do you use? Silicone based? Could you give the name please.Also what was your procedure: steel brush -> grease -> reconnect? Yes, I use Vampire RCA for phono, unofortunately the golden layer is not very durable, on one...

Besides Romys short list of features:
1) A preamplifier shall be modular - the ability to insert n quantity (maybe 20?) of input cards on a backplane (for phono MC/phono MM/line level/Balanced/Single ended/TOSLink) as well as be conf...

Jarek, what you describe can happen if anything with voltage touches the chassis, or something might be arcing across a very narrow gap. I have seen part leads that went too far through PCBs, also carelessly fitted stand-off. Even the axis of a choke...

I've tried even placing a cheater plug on the PP+ unit and still get the hum. Why can everything be plugged into another conditioner or everything into the wall and all is dead quite BUT plug either the phono stage and or the TT motor into the PP+ un...

Ah, think of it this way. Imagine floating the input to your ET step-ups. Don't ground it. Let the primary and phono cartridge float. This is a similar situation but far far more sensitive. It's a mind game to make it ea...

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...

Also, Guy, I juts received my favorite Classical Record Collector” magazine (the only one magazine that I subscribe) and they had an advertisement about the FM Acoustics Phono Linearizers. This baby has virtually unlimited capacity to be tuned to any...

Well, there are many full-function preamps. It is a common tendency nowadays to make an add-in board with phonocorrector to a line-function preamps. Recently even the full blown tube preamps use the j-fet phono-boards.
Interesting that I would like...

Do I remember that a big part of Romy's choice for a pre-amp was based on the specific needs of his DSET Milq, with it's inter-stage X/Os? And do I remember the Placette Active Pre-amp has consistent, fully buffered 10R out?...

I just ran across this quote from Mr. Fremer, circa 1999, and I doubt much has changed on this front:"Sitting in my listening room auditioning this $3995 Premier 15 phono section from Conrad-Johnson—a process that I made sure went on for months!...

Let's see what Framer will find next...got a mail from Australia that Continuum has Production Problems. Also some master brains left the company...Well, I did listen 3x to the big Continuum, 2x it was more or less defect. The last time 1 channel did...

Paul, perhaps I did not understand your posts correctly, but observing your battery obsession throught the time I cannot get one thing: why the freak you are hooked up to the idea of a small, neat battery powered phonostage so much that you start to ...

Hello Romy A sleepless night had my all-but-derelict brain going round and around the phono stage and, of course, more questions than answers were thrown up. Did you and your designer friend first try an intermediate version of the 834 circuit which ...

I have to say, this might be the "best" review by MM that I've read. Certainly it is more thoughtful and less hysterically fawning than usual. I agree that with a stock Jensen SUT (if, in fact, this is what he's done) Lamm might have gone too far w...

Wow. What can I say? My intention here was simply to propose good news to owners of heavy Micro Seikis - to consider trying a CU-180 on top of their big platters. Somewhere along the line I had to gently correct Romy on a point has been common knowle...

[quote user="Romy the Cat"] I guess the reason why the arm lost it’s bass is ether the problem with arms or the problems with arm cable. [/quote]The phono stage has been ruled out?...

TKD has also high quality Parts which are not listed in the catalogue. I heard, some personal contact can be helpful to get their best units. They will be built on custom order only, in batches, when they made it, it is done. Price, well, when you ha...
