Dear Romy. Is it possible to shorten 2000hours running time by using high output MM cartridge?Best regardsarmen...

I need to note that MicroTTs, American Sound and a few other TTs with very heavy palter are complicated subjects. From one perspective a heavy platter is the key. I remember years back a few years Lechintsky published mathematical equivalents of TT ...

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...

I have heard several Tannoy speakers in the past, but have never heard the quality of sound Romy has obtained with his brain child. I don't know whether it is the speakers alone or his setup which has allowed his system to enthrall so much more than ...

I started in hi-fi with LPs and I have never stopped using them as my principal source for hi-fi. Some time ago I decided that master tape was better than vinyl, but I could not afford to go that route; so I settled on the next best thing: a cartrid...

Alex, the best version would be the first (Series 1) version but these are very rare. Next best would be the pre-Improved Series 2, having metal knife-edge bearings. The Improved would be OK for light-weight, light-tracking MM carts, having been deve...

before you gut it. How funny would it be if it turned out to be any good, or even not bad?Since they all seem to need endless hours of tweaking, who knows, maybe you've got something here.In any case, the chassis looks quite solid, and the indus...

Hi Romy,I think you may be struggling to get 10-12db of gain out of a spud amp (the term is a play on "one tuber").... May just about get it with 6C45.... remember you will be stepping down something like 12 to 18:1 on the OPT.best case: 10db require...

Lots of free-for-the-taking info about fringe stuff, including high-dollar tube sockets, on Dennis Boyle's sites. I built some of his Advantage II design/spec cables, and they work very well indeed as long as you don't really need shi...

[quote user="be"]I recognise your observations about the Ag vs. Cu sound, but instead of mixing the two materials I think it is better to change the diameter.I experienced 0.5 mm silver wire to be too thin soundvice, have you tried 1.0 mm or even mor...

N-set, if you have an unused circuit in the apt., then its neutral may be an acceptable ground path (neutral stays "on" even when breaker is "off"...).Re, the phono calibration, I have expounded the SRA at length in the "Vinyl Ceremonies" thread. As ...

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...

In the past there was such a concept of full-function preamplifiers that included MM and MC inputs. With time such devises die out and nowadays it is VERY difficult to find a full-function preamplifier generally and a good sounding full-function ...

Well, why not go 1st order with those little "woofers"? And I suppose you will be glad that you've isolated the MF, too.Unless you just get lucky, it looks like the MF/HF XO might be dropping. I am not familiar with the 2105, but dependin...

Stringreen, what an interesting series of posts. I generally enjoy musicians' takes on hi-fi, especially as these relate to sound (versus music). In all performances there are so many things to listen for and to. What I have mo...

Hi, George
First off all I have to mention that I use Max 282 as my “second” arm. I mean my best stereo cartridge I use with 3012 as I feel that it has more interesting lover bass and upper bass then 282. The 282 has slightly hollow and slightly bor...

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...

Roman,
I can't follow most of your arguments. There are many ways to do things and to lay out the architecture of a system. This line/phono combo was designed to work together and to the given requirements. 75-85 db of gain ? Remember thi...

I do like the assembly. I o not fine it messy at all BTW. I would like to have inputs slightly closer to the grid of the first tube. I would also run the heater wire further from the circuit and decent them from higher distance. With all in place you...

Mark, you certainly have a point – if you used the techniques above did get sonic benefit then that all that shall count. Well, sort of. You see VTA is no more than the angle under which the needle hit the record and for all intended purpose it is no...

[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...

Adrian, I wrote extensively about the TAP in its own thread. Given good electricity, the pairing of K&K and TAP is a pretty clean gain path for the cartridge, with far more range, color, etc. - everything you'd want - in the end than the pr...

[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...

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...

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...

Sometimes ago I received an email from a NY guy that I know:
“I borrowed a friend's Sansui TU-X1 and just like I heard them at your place it sounds fantastic! What is it about this tuner? There is such an ease to the presentation and no distra...

***The proper loading value is difficult to say without knowing your system, as it is partly a preamp and ultrasonic RF issue as well as one that involves the cartridge and audible frequencies. Some cartridges have frequency abberations within ...

I did not shoot for the Collectors' Holy Grail to start, but I looked for and bought a +/- "generic" version. The 3.5" I bought are unusual only with respect to their atypical (smaller than the usual 4") cone. They are 88.9 mm, as I recall. Otherwi...

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?...
