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 ...

Romy, how are things progressing with this? Is it all done and dusted yet?
Can you compare and contrast the sonic differences between this high Gm contrivance and your previous EAR 834 variant?
All the World is waiting for the sunrise....

I heard the 'cole' LCR phono by the hifi supply recently at a friends house and it sounded ok, the Allnic 1500 that I am using at the moment is the best phono I have heard, and the price is extremely reasonable for the design, valve regula...

Cello HI I have only heard the Cole for a short time, so it wouldn't be fair to compare, also I really can't say to what extent the LCR circuit contributes to the sound of the 1500, the Allnic is very dynamic, has high resolution and makes inst...

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...

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...

The last couple days, having some controversy with Allnic’s preamp , made me to go few times to Allnic web site. In here I was reading the information about Allnic Verito MC Phono Cartridge.

I am all set with my reference arm but my dally arm with SME 3009/Otophone SPU Classic severely underperforms in my view. The arm use Otophone SPU Classic that is all together is OK balanced cartridge. Nothing overly exciting but more or less neu...

I was just thinking.Isn't an riaa filter just a line level crossover for one channel (times stereo)? So what you say makes total sense....

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....

First of all, thanks for additional detail. As mentioned I can speak only for my Fidelity Research XF-1 (30dB). Loading it on secondary as you mentioned, it ALSO damps the trannie - result in my case: less resolution. Primary loading is MUCH more sen...

|
...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 ...

[quote user="Jorge"]Shouldnt your SUT be placed inside the Phono stage directly? that is a real advantage. [/quote]Jorge yes, the SUT/SUT's are definitely in da house of the phono--ther are some pics up the thread.I'm not convinced foil is a good ge...

Paul McGowan look like will be releasing soon PS Audio new devise NuWave Phono Converter. Read the release and see what it is. http://www.psaudio.com/shop/nuwave-phono-converter/ Unquestionably it is a very proper product, or I would say a family of ...

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 ...

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...

Vinyl almost died after the launch of CDs, but today the popularity of vinyl playback is on the rise. Music stores are selling more music available on LPs, and many audiogon systems include turntables. So where are the full-function preamps? Before d...

Paul,I agree 100%. Well sort of.....Can the idea of the overengineered, atomic reactor power supply with water cooling really offer someone just interested in great music a "better" solution?I think for many, the technical superiority is at least as ...

I am with you on this one. I am also very suspicious of gigantic, 4-chassis phono stages if only because I just wonder why the need for all those damn noisy parts, along with concommitment connections?So it really pisses me off to admit that th...

The 'Death' phono stage. I like it, it may have legs!...

So you showed off with your rocket radar something called Omni Gone here:http://www.whatsbestforum.com/showthread.php?6068-Omni-Gon-The-Final-PhonostageWhat caught my attention is the switching of the phono inputs (since there are multi SUT'son board...

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...

[quote user="SOS "]What about this issue of humming, this is a reoccurring theme that has not been addressed. Even my own 2000+ unit I sold to a gentleman that owned an original 2000 unit who said he would be able to figure the issue out had the humm...

Here is a snippet from an email from Jonathan Carr (Lyra cartridge designer) about objectives and considerations regarding cartridge loading. Most of this is old news, I only re-post it here as a convenient synopsis on this most misunderstood t...

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...

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...

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 ...
|

Thanks for alternate driver idea, Romy. Sounds interesting.I certainly do not need all the gain from the ML2 along with my AI M3A phono/pre-amp, so I will give the 5687 family a try once I figure out a decent, fool proof pin-out adapt...
