Hello Roman,Hola from Hong Kong! How are you? Haven't been here for long time. I have a question at the back of my mine for long time, and it may have been covered elsewhete in your blog before. I am asking it here but do point me to the thread if it...

Hi miab, my room is approx. 6x5x4m, so although quite small by North American standards (not UK!), the ceiling is higher than that of most modern houses. This seems to play a big part in the LF performance of any speakers in this room. I currently ha...

Romy,To clear up a few things about the Kilimanjaro RCA1428 clones.The B&C DCM50 is a modern, neodymium clone/copy of the RCA MI-1428B. It was designed and built by B&C in Italy after Bill Woods of AHhorns talked the CEO into it. The DCM50 is...

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 ...

1. The less we have to fill in for the brain to reconstruct the original event, the better it will sound. This has been proven by psychologists for all of our senses. The closer to reality the sensation is, the less the brain has to work, the more re...

Ah, I think I got a good break. Just had a short listening session. And it did sounded very fine, with no compression and with all those gorgeous hallucinations in place... It almost like good versus bad electricity but I think I have a different pri...

Jarek,I am a professional musician, and am very much in "tune" with creative processes.A random result is not automatically "bad", but because of its "randomness", there is a lot of ground to cover BEFORE one can even think about further steps. Case ...

Feeling less depressed this am. After returning from Romy's and coming down from the high produced by his sound, I made the mistake of turning on my system, which had sounded great the night before. Within less than a half hour I turned it off and we...

[quote user="RF at Ona"] Romy,I might have overlooked something on your site but I understand that your ULF amp is driven directly by the preamp line stage. If that is the case, you may want to consider an old technique for integrating subwoofers...

[quote user="guy sergeant"] In your earlier piece about how to use the S2 'properly' you wrote
"Whatever happens between the 400 and 2,5 is pretty much unnecessary for you garbage. So, get any known to you soft capacitor of 3uF and place it in serie...

Hi all ! [quote user="morricab"]
Hi Romy,
Could you explain a little more about the amp? If I understand you correctly it is a 1 tube stage with solid state (Mosfet or Bipolar??) output. If it is Mosfet then it is likely to be running w...

John,
I do not think that it should be arguments at the level like: who could hear differences or whose playback sounds more realistic. The man had his point, agree I or disagree with it is irrelevant. The question should be not about whose views a...

[quote user="jamesrm618"]The Vincent SP-T100 looks close "The SP-T100 is a hybrid mono block with tubes in the input stage where voltage is amplified. The power output Amplifier circuitry works without feedback." Nominal output power Class-A 8 Ohm: 1...

Hi,[quote user="dazzdax"]Thx for this well written and highly educational piece Thorsten! It appears that Romy is not very fond of the Audio Consulting transformers, could you give your opinion regarding those? What is your opinion regarding the use ...

I was traveling yesterday and away from the computer until this evening. I'm glad to see my post as the source of controversy and even cause for a public flagellation from Romy. I don't know whether to laugh or to cry. Actually, I d...

Chris, I'm not Romy but I've listened to some of their products -- about which I'll talk later. First:[quote user="dazzdax"]Hi Roman, FM Acoustics amplifiers from Switserland have been regarded by many audiophiles (mostly the ones with lots of money)...

Terry,
I did found that PP amps were good to drive BAD compression drivers (with ceramic magnets). The irony was that the better amps to drive the ceramic magnet were not just the PP amps but the solid state PP amps. Do not ask me why – I do not kno...

one would take full advantage of what can be done in the digital domain so that the horn mouths could be arranged, not for time but to clean up their other interactions. This would be digital the entire way, solid state music files, digital amplifica...

[quote user="coops"]Mainly because of my young daughter I have been listening to mostly solid state amps, I have enjoyed 'Digital DoMain's' B1-a VFET, and am now listening to a German 'Audioprojeckte' CA10, 10 watt class A design, ( I will post a...

Actually I don't find it surprising that engineers don't realize the sonic effects of their engineering. Remember all the indignant articles and letters they wrote about how great solid state amps with low THD sound and how lousy tubes are. In the ca...

[quote user="Romy the Cat"]I do not care about all of Nilsson Pass amps; I feel that all the same and all are very sub-qualified. A few years back Mr. Pass went for his low-powered SS single-ended amps and they might be more interesting. The Cat[/qu...

I am sorry I do not want to pollute the PP2000 thread with battery options.Right now I am in the process of testing a lot of different comercial amps to see what I will stay with, or which route I will be taking with my system in the near future for ...

6) Ok, the first half elephant in the room – the dynamics. Believe me or not but PP3000 is more dynamic then PP2000. It was very sensible from the very first note that I heard from the PP3000. I do not know what to say ...

Romy, some people that know me will say "yes", I am not sure... Of course no, not the Rowland to drive my horns, this is the amp ...

This is something I've been chewing on for quite some time and finally decidedto make it happen: a serious Stax headphone amplifier.I hope I can use this space as a sort of a blog-report on the progress...if not feel free to remove. I've been "forced...

Thank you for your answer.If I understand well, In purpose to do something realistic and good sounding. I should use at least 2 amplifiers (one for high frequencies and the GM-100 amp for low frequencies) with a tubes active filter at the inputs of e...
