Romy,The common mode noise will lie between 5 meg and 8meg or 8 meg to 12 meg depending upon whether it is forward or backward mode working. It does not have much to do with the 30Kilohertz.It is possibly true that one unit may have filters to keep ...

... on the (or your) kind of view. Some time ago I had a nice conversation with the marketing manager of a very exclusive and high priced Japanese Brand in a Exhibition Show. Of course, all talk about Sound, a bit more from this here, a bit less from...

Bill, of course I supposed the DSP-free sound would sound better than processed to me, based on my experience. I just wanted to know how you felt about it, when it was put like that. I went to big SS amps despite I prefer the sound of small SET amps,...

...in my case the problem seems to be a GND loop *inside* my End of Life phono. Thanks to the continous help of PP Richard, I started to suspect the terrible noise I'm getting actually may be the charging voltage of the PP el caps (indeed it is 100Hz...

A slightly lower filament voltage is okay for a coated filament (not for a Thoriated-Tungsten filament however). There was some testing done some time ago on this and findings indicated an increase in tube life and lowered distortion. I just don't re...

Yahoo! I was able eventfully to educate myself how to get out of the “Melquíades” the sound that I needed (using some blood injections from Dima)! Now the project with the “Melquíades” amps is slowly converting from a labor to a pleasure!

Last week I sent my DAW’s DAC cable for refueling. The FM programs are slow – the concert season starts in a couple of weeks and everyone are resting now. So, I am spinning some records that made me to pay attention to the status of my analog. What I...

I am very jealous of people who buy a decently designed turntable that does not cost an arm an a leg, and can be satisfied with it for life. That first step they took, going from direct-driven, plastic tonearm and throw away cart TT, to a belt d...

I have for a month or so the Allnic H-1500 II SE Plus phono stage sitting in my home. It is two chassis phonostages with tube rectification, tube regulation, LCR 600R filters, own Allnic step up transformer for MC needles, 5842/417A in gain stage...

Yes, the fragility of the marking is a very good sign on some German tubes. Still, I do not see why the people who would like to fake them nowadays could not reproduce the washable marking. They have learned how to make the diamonds under the bottom ...

So I decided to try some of the mods mentioned to my semi-recent 834p w/ MC step-ups. It all started with C1 and C7...but then i got into RIAA, upgraded diodes and filter caps. Well, everything should be just stellar on paper but...now I have a hum t...

The Weiss AFI1 interface is measuring the following clock rates (in KHz) from the Model Two:- 44.122- 88.244- 176.488AND- 48.000- 96.000- 192.000Does this imply that the 48x clock is more accurate than the 44.1x clock in the Model Two? I'm assumi...

I understand the rational to get TL0, even though I would not do it as now if I start fresh. The perspective that I am trying to bring is kind of DAC related, If you get TLO and would go for “ultimate” DAC for that transport then you might discover ...

Bumping up this very old thread but I bought a Yamaha T-2 in October via that well-known auction site here in the UK. Even through my humble system I can tell it is a cut above all previous tuners I have heard. Admittedly I have never had anything re...

Somewhere in 1997-88 I bought a hundred 6C33C. I believe during those years the where more expensive then now and I paid around $7-8 per tube. Over the years burning the 6C33C in pair of VK-60 (8 tubes), two pair of Lamm ML2 (ML2), ML2 with Melquiade...

Hello all,Some time ago, I bought a pair of very early production ML2s for an ongoing horn project (see "Note at end").Rather than just let the ML2s sit and wait for the horns to get done, I of course tried them out with my "normal" 89db/watt@1m spea...

Actually I think I was clueless until a second part of 90s, perhaps the late 90s. You know it is kind of strange: I did audio kind of all my life but I never knew, cared and was a part of the high-end hobby. All those valleys and summits of audiophil...

The whole room (L-shaped) is larger as you all noticed, but as Roman saw in my Blog , the listening space is smaller - i.e. about 6,5 x 4,5 meters with low 2,70 ceiling - and is a perennial work in progress... yes, the Stereo Lab 1000 hz is a true wa...
