Hi Peter,

I was going to accuse you of being a CAD wiz until I seen the fold lines in the image. It looks like the model for the (in)famous Potter/Pass A75's.

Rodd,

The heatsinks look similar, but the number of output devices doesn't much. I saw that picture tonight and couldn't resist not to post it. The number of devices is really impressive. But I was expecting more power. It's only 1000W into 8 ohms.

The caps have printed Black Gate at the very top.

feel free to answer!!

I just wished to know what people think about numbers and if they think that there is any relation between numbers and sound quality!

I personally think that numbers has no meaning, not even the rated output power of an amplifier (build a 100W amplifier, one with a 200VA transformer and 20 000MF capacitors and the "same" amplifier with an 800VA transformer and 60 000MF capacitors. They will not sound the same and they have the same numbers).

Best regards

Yuri,

I can see where some people may be offended by this and the other thread that you have significant input in. In the other thread, you have included what seems to be quotes from your advertising literature. This thread was started as a marketing survey. This certianly crosses over into what might be considered spam. It's a plus that you have at least included your name here, but you haven't in the other thread.

IMHO there needs to be a stronger connection to DIY audio in your approach to your questions and replies. This is particularly true for people, like yourself, who clearly represent a commercial concern (and even more so because your company manufacturers amps).

I'm sure the moderators are on the fence about whether to pull these threads. I not sure if they should. There is hope for you, but you should be more forthcoming with the information to the DIY community. You could be a valued contributor to this forum, but instead, your just plugging your products and pumping us for marketing info.

I usually do not participate in surveys, but if you were to give your opinions on the matter, I may give mine in response.

Hi Rod,

I'm not pumping anybody for any marketing info!

It is true, as a manufacturer, I am interested in your reaction to numbers.

Let me remind you that I already wrote that I do not trust in numbers and I gave several examples!

When you speak with some consumers, they say so different things about how they make up their mind (not only buying amplifiers) that it can be a great learning for us, manufacturers, to read and perhaps learn from "all" of you, your deep thoughts!

I placed some information out of our web site, not make any direct adverting, but to give an overview of our next plans!

Out of those, everybody can react and give his opinion.

What can everybody can read at the time being, is that the best of judges is the ear!

I also wrote that somewhere else…

If you read other threads, some are fighting as mad about the fact if the DF ‘damping factor) is important or not (I just think it is not for several reasons)!

Best regards

Guys, I say lay off Yuri - he is asking perfectly reasonable questions. (but no more yelling at the keyboard ok Yuri ?)
He is trying to guage what sounds good to the most of us, and how so - like different distortions and other characteristics that combine to yield a well regarded amplifier.

Except for Dave no one has really answered you.
My experience is that different amplifier applications require different orders of priorities.
For pro useage, indications (clip, temp, fault) and comprehensive protections (thermal, shorted load, fault) are mandatory really.
Clip indication is needed on domestic/audiophile gear imo.
Of course one of the overriding factors is the nature of the sound of the amplifier under all conditions and very important is the sound under high level/momentary clipping passages.
Also how the amplifier changes with different sources, cables and loads - a clean and source/load invariant amplifier is the objective.

Any added HD spectrum is important especially in the higher order harmonics - even though these are usually very low level they add a disproportionately strong sonic character.
Lack of IMD is mission critical especially at levels up around clipping, and this is the strongest like/tolerate/hate component to my ears.

Once you have achieved this you can modify some things (tune it)and bend the sound to get a characteristic that appeals to the appropriate ears.

Regards, Eric.

Hi pss audio..

I have known about your amps. for quite sometime...the dc offset and soa protection circuits are suspect i fear....

There are a few other significant niggles to my mind at least, but i think these are covered comprehensively in D. Self's book:
'audio power amplifier handbook'..third edition.
