[quote user="anthony"]Have put all my DHT's on the curve tracer to see if pairs can be matched for preamp duties. [/quote] It was very interesting to read about all of it. If you have a socket for YO186 then you can accommodate all 4V tubes and I si...

It is complicated. Any tweeter is different and the RAAL’s “Water Drop” tweeter is more different then others. Almond any other tweeters that I heard this tweeter has something absolutely unique- it has no annoying upper MF nose. When I asked Alex to...

Romy, I do agree with all your comments. It is true that the magnitude of the rubber taste very much depends on the crossover frequency. I used them below 64Hz, but with first order filter, implemented before the amp that drives them. With that kind ...

Tim, you see I have no specification that the cable might be built I have only requirements. I have no idea what kind cable making specifications should be consider in order a cable yield this or that sound. Purist does build custom cables but primar...

Yes, it is a common deal and it is possible very frequently to get a bunch of the Vitamins Q for very little money. Thanks God that no one from Sprague pay (paid) to market-makers to drool about the Vitamins’s sound and therefore the wide majority of...

I keep thinking about the strangeness of my phase inversion.
I still do not think that it should be this way. My leading explanation is because
I did not implement the crossover precise. If the crossover called for let way

This weekend I made an interesting experiment. I had a visitor yesterday. The gay is not what I call overly critical and overly demanding listener but he is not a typical Audio Moron and has from my point of view a proper and sane react...

Yep, thanks.
I still do not know why you feel that I will not exploit the “ringy dustcaps” on the Malaysian bass drivers; in fact I never gave up on this idea. I preliminary concluded that my MF channel might not go lower then 700Hz but I did not sa...

[quote user="jessie.dazzle"]While reading of your progress on the 6 channel amp, I was thinking ahead, and how I might approach the building of such amps as separate projects for each frequency band (separated physically as well). In my particular ca...

(Romy feel free to move this post)[quote user="Paul S"]N-set, I understand you do not mean to hijack the thread with the Axiom, so I actually tried to make generic and/or thread-related observations. I don't know the 6E5P, but generic issues with sp...

[quote user="Paul S"]Romy, isn't this the first time you have tried the film caps for PS and the "ALL-NEW" "SUPER-SOFT" diode bridge? I would certainly go back to known quantities before I did or un-did anything serious. Not that I always...

If to look at the Melquiades schematic in the channel “A” you will see 78H first order low pass filter.

[quote user="hagtech"] I run the driver tube at 170V @20mA. I don't think you need to run this tube at high current. It is very linear with wide signal swings at this bias. [/quote]
Good operation points for use it as a driver. You might...

After 4 days of suiting in boxes in my listening room today is my day off and I decided to dedicate it to play with the new Pure Power 3000+.
I desired to use just records and connected all amps, preamps and phonostage to ol...

Actually I care less about the design philosophy in this case but rather about the result. Obviously the 150W-200W (200W?) of Zarathustra’s pure class A would be completely useless for my horns. I would like to have something to drive with that amp a...

R,
I note you calimed a fondness for certain softdomes; looks like there are some newer scanspeaks that may have the tonal qualities of your favoured types but with higher sensitivity, which will match the Focal well.
Eg: D2904 types at

Dominik, Jessie is right - it is irrelevant the precession of your profile if you horn does not go to high into HF. The LF gain of upperbass horn happens in the first half of horn anyhow. I do not insists that I am right but I have a hypothesis that ...
