In fact am not only planning to try an electrolytic capacitor as the LF Milq’s coupling (if I found one with low linkage capacitance) but I would also planning to try the “my proprietary” cooked capacitors. I have to admit that it sounds very s...

I have never used EL34 in triode, but I think it is not hard to find acceptable examples of this fast, reliable tube, and with conservative bias it should let your 6E5P "shine through", if that's what you want. Nothing like 811, 845, etc. in this re...

[quote user="Paul S"]Lamm did choose to use some of the driving ideas from his proven SET amp…[/quote]Yes and no. ML3 design wise, as I understand is, in fact is not as interesting amp and it might be otherwise. Vladimir went for the target marke...

Regarding L1 and L2 outputs and bi-amping:

Well, I screw-in today the S2 with filed-coil into my horn. I decided to drive it with 2.4A. I used a regulated DC PS and did not employ my prepared for this tusk 4.2 Farad capacitor: the voltage is too high for my cap. The current gave me a ni...

Apparently, TTs are so mysterious that anything goes, as long as it's long, convoluted, and circular. Multiple DC motors "make sense" if one starts by believing that an AC motor naturally slaves to its sine wave and polarity, and that this behavior ...

If only we all could succumb to the realities of compromise earlier in life instead of thinking there is actually a Holy Grail Perfect Solution to any problem. Audiokooks would be much happier if we would.Kind of like polarity - no one really knows ...

OK, I have found the problem I had with my digital and
analog crossovers, now everything is consistent. It turn out that my contractor
why built for me the IB manifold confused the polarity of right and left channels.
I was not able to use the pha...

One of the things that I picked up in this thread is the fact that if you use 2 PSUs in series, the sound degrades.This is typical of one unit generating common mode noise and this adds to that produced by the second unit.Even if you run them in para...

Well, Jessie, I think you're exercising a wishful thinking but you have, I think, a wrong subject for your thinking. Neither Lamm nor any other high-end manufacture care about result as a concept but rather a result as product. A product b...

I am of course guessing, as to how you got the sound the way you describe it. This "off-set" might be pleasantly less then what I had in mind. It initially reminded me of an effect by having no impedance correction (Zobel) in a midrange driver, and o...

It is quite depressing. I got the panels install them to the speakers, mounted the drivers, staffed was there boxes and connected. I do not think I needed to do anything else. Is the sound to supposedly horrible and I am little bit puzzled. The s...

Domidaw, you are looking at the right things but there is something to consider: when you put a resistance meter across a discharged capacitor you see a low resistance initially because the battery in the meter is charging the capacitor a little, so ...

CJ Yes I have assessed AC polarity in my system.Romy says "I took today my large
3kW isolation transformer and place it between my dedicated line and
PP3000. I lost my lower bass, simple as that. "Speaking of isolation transformers, I have not h...

Yes, this is kind of strange. This is a cheap Blue Ray player; I think it is Sony BDP-S790 for $279. It played anything and supports live stream for pretty much anything. It is very comfortable to have it in opera room as video source. The picture is...

[quote user="Stringreen"] My opionion is that there is no absolute tone - just as there isn't an absolute sound. [/quote]I disagree. I do not know how about the absolute sound – it would be a difficult subject but “Absolute Tone” is not only ease be ...

As I said I do not use phrases “soul” of “soul-less”. Perhaps I have enough grip of it in audio and do not need to trade “soul” in place of plate currents or polarity of cables. Sure, we all chaise the self-selected ghosts regardless what we do. It ...

Ok, how to start. First of all we have to understand that out subject of attention will be a region between approximately 80Hz and 500Hz or something that shape the fundamentals of the “melody range” within your playback. Search my site I have writte...

Thanks for your quick reply. I have been to assistance audio`s website, however was unable to find such model, but is possible they just disassembled the tweeter or whatever.This is really interesting news, about their violin reproduction, me too wou...

Paul, after a month of vacations I've tried you advice:[quote user="Paul S"]If you can do it, try isolating both cases/chasses from your "ground plane(s)". Use one inclusive "ground plane" for both the PS and the gain/RIAA sections, and ground this "...

A long time ago Clark, with utmost kindness, helped me understand polarity, and opened doors for a deeper understanding of music. And also how to be a respectful person in this world, without compromising. In his last novel, All That Is, James Salter...

This is very interesting, Anthony. I do think that absolute polarity has own role to play. Also, do check the DC that might be sent out of your preamps, certainly with Placette and with your 10Y before the transformer. Chas it with disconnected Milq ...

...I hope y'all are attending to AC polarity alignment, else many of your decisions may be erroneous. I've written so much about this perfectly audible phenomenon that I don't feel like doing it any more, so I point you to an excellent comprehensive ...

Denis,
There are objective characters of electric wave and deviation from it sinusoid profile impact sound. Leaving the HF noise aside I would say that there are also some unknown characters of electricity that impact sound. What you report shell no...

[quote user="cb"] The bias voltage I get on the 6e5p is around minus 4.4v on both the circuits. This is with the inputs shorted. With the inputs connected to adjust voltage to 0.0mvdc, I get a reading of plus 0.4vdc. This is with VR1 set at maximum (...

Here is another advantage of multisampling and DSET in particularly. There are many moments in amp that in one or another degree affects transients.The capacitive coupling for instance works fine but as long the amp sits in class A1. As soon amp hit ...

I thought the B1 was Yamaha's V-FET and the B2 was a later "hybrid", but I suppose both are Vintage Sufferer's wet dreams. I have never heard either amp, anyway.
Yamaha B1 and B2 conceptually the same amp. B1 is made only with one polarity V-...
