Robin, I'm not at all certain that my new speakers are "source tolerant", because I have "taken steps" all along to "ensure" part-to-part compatibility. I have tried to "sync" my phono and CD/DAC as much as possible, and the main thing I wanted from ...

I am using the Celestion Axi-periodic compression driver in the KLIPSCH K402 horn which I have boosted considerably when I noticed that the top one and one-half octaves were barely working when playing music so I figured WHY NOT? and it works just f...

[quote user="Romy the Cat"]I did not know that Lynn Olson and Earl Geddes involved in Levinson’s operation. With all disagreement with those individuals I thought that they are smarter than to deal with Mark Levinson. I hope they did not give him an...

[quote user="Lx_"] Well, this is consistent with the behavior I have. I can hear electrical devices behind the PP, especially those of the switching PS type: computer screen, laptop charger, DSL box, printer, SAT decoder... Good luck finding electron...

I used to have a few musician friends and played a little myself, but they were never really interested in audio, they did have a system but no intention to sit in the sweetspot or anything of the sort, we used to go to concerts and they would carry...

Hi Romy,I have a couple of theories as to why I wasn't able to get to the "VTA sweatspot" before I tried the microscope method. The first is that my "baseline" (using the ice skate tool that wally sold me) was so far off that the range I was workin...

[quote user="CO"]Why such a wide angle? To keep the highs evenly spread and match to the angles of other chanels ofcourse but this will call for much more attention to room setup/treatment.Wouldnt this also lose some of the horn magic by letting the ...

As I told, I’m generally not a fan of the Shostakovich’s orchestral music. There is in Shostakovich’s “large music” a constant sense of vulgarity, peasant intellectualism, humiliation and a sense of blown-up meaningless artificial musicality that ver...

[quote user="Andy Simpson"]Having made my last comment based on what I 'heard' via my laptop speakers, I took the clip to the workshop monitors last night to have a further listen - not to examine the weird processing, but to come to a refreshed idea...

[quote user="Romy the Cat"]Andy,
Yes, it is what I was thinking: they had many microphones and before the blast they turn some of them on to highlight some sections or instrument but the microphones were too hot and when the blast went off it was ...

Romy,
Air core is ok, but. 1. Self inductance in an unmitigated field clumps. You can easily see this by unwinding a hockey puck style air core inductor and measuring the inductance with each turn removed. Never will you have the smooth loss of indu...

Yes, the last cap of power supply much be on the side of load as it shell have a short path to ground. Without it you will have “less bass”, more crosstalk in case it is a stereo amp with single PS and a few other negative things.

Along with last remodeling that we performed in Opera Room the room is becoming more the most pleasant room in our house. In fact we spend now more time then in listening room. We eat there, we watch films there. Sometime we watch TV there. I sleep t...

[quote user="Paul S"]Yes, Bud, I agree that the most common problem for the full-tilt regenerators is that they begin to exhibit various problems in direct proportion to current demands. And this seems to be true even when they are used "below capac...

Spoke last night with PurePower people and have good news.
First, after the “agonizing research efforts” (satire) the APS have discovered that source of fuzziness that I reported above and claim that they have a very simple fix that would not requir...

And I do not mean this as a criticism.I had for some time an "original" Music Reference RM9, which was made by another well-educated genius, Roger Modjeski. The RM9 was AB PP with adjustable bias and feedback/gain, with 6DJ8 drivers and a ...

Thanks, Eduardo, very interesting. The YL 75000 has no phase plug and 70Hz with 1” trout. It look to me like a conventional diver. Which beds a question: if to reduce compression with our classic drivers, loose plug off and reduce power then can we ...

Amir, Romy was actually very specific about why he was critical of Melquiades/Macondo. Even in old posting, he made a point of mentioning that he very much knew what weaknesses he had. To be honest, I believe that his real motivations for change are ...

[quote user="Paul S"]Romy, is it a goal to make the horn strong enough to raise one end or turn it without having it fall apart from its own weight?From your earlier descriptions, I expected to see at least one continuous piece of plywood bridging th...

This is something I have been at for the last few years, I have tried a few drivers, at the moment some of my favorite are the vintage RCA MI 1443, yes filed coil and some funny cone diaphragm, they are used from 500 hz to 5 khz with a Fostex T...

[quote user="darkmoebius"]I asked Jim Hagerman how long it takes to break in interconnects, power cords, speaker, cables, and preamps? He replied - "Usually about 40-50 hours on a FryK. The amps are fastest and get most of the way overnig...

With the omnidirectivety paranoia many people might loose from attention that fact that in order to be good omnidirectional speaker the RAAL new speaker has to be just a good conventional speaker first. The new RAAL speaker (does it have a name?) as ...

Well, it is not necessary a fully qualified urban legend as the problem does take please with fixed based 6C33C but..... only under certain conditions. I have written about it a lot on my site but will very briefly recall it again.

If you follow this thread and my successes and tribulation with PurePower regenerators than you remember that I had problem with sound running two PP2000 for right and left channels. So, I had everything, including my DAW plugged into on PP2000,...

[quote user="Mark Donahue"]Mani, Yes, the files were created using the HDCD Model 1 AD converter and you will actually get improved audio if your DA converter properly decodes the HDCD (Even at 88.2 kHz /24 bit!) There is information about the filter...

I really enjoy this site. Romy has a fresh view that is actually easy to understand, if one simply reads instead of interpreting what he writes.Still, a view from "higher up" is something that many of us are not privileged to. Looking at the major co...
