Dussun amps

I've read several reviews of these amps and integrated amps and was just wondeering if anyone has actually heard them. Their 2 top models, V8 & V6, are "hyper Class A" (whatever that is have outputs of 250 watt and 150 watt, respectively.
Reportedly they run so cool, for being Class A, that you can put your hand on the heatsinks and leave them there. The speaker terminals look like terminals on a 1950's Tektronix oscilloscope, I once owned. Check these amps out at www.dussun.com. Is anyone familiar with these items from China?

Re: Dussun amps

Just reading the retarded writings of messed up engrish on their web pages makes my head spin. What are they saying? I tried to comprehend the ramblings of the amp description......why bother?

Re: Dussun amps

I've seen this before on low end devices form China - i.e., the right channel terminals on the left side of the amp and the left on the right side, lettering backwards and/or upside down, etc., etc. Beings these amps are being marketed as "high end", and not cheap, I figured they could get simple things, like labeling, correct. But if it sounds good...

Re: Dussun amps

It sounds like they use a variable or sliding bias on ther output stages. This would lead to cool running under most conditions.

Upside down so when you are looking over the top from the front you know what it is.....Which is correct? When you are standing in front of the unit or back, to denote right or left out? Many times you do stuff from the front. over the top?

Re: Dussun amps

I had the opportunity to hear the V8i and the DS99 this past weekend. Running the V8i as a standalone amp connected to a Blue Circle preamp running Focus Audio FS-888 floorstanding speakers, the synergy was honestly pretty bad. Did not get a chance to run it as a standalone integrated amp. However, the $500 DS99 integrated amp was a revelation driving the Focus speakers...extremely high performance, and IMHO could compete with integrateds far above its price point.

Re: Dussun amps

JoeE, I'm not familiar enough with "variable or sliding bias" to know how it works. Obviously it keeps outputs running cool but what about side effects on sound quality.

DUP; "upside down...over the top from the front", I'm too old and arthritic to be getting in such gymnastic positions.

PhilNYC; In my recent search for new equipment I listened to numerous devices that were made in China. The audio quality on all of it was very good to outstanding. All the pieces I heard sounded as good as or better than equipment costing much more. I recently read that some well known high end equipment (domestic and European) are actually designed and manufactured in China then the appropriate logo applied. I recently purchased Music Hall's A series amp, tuner and CD player. These items sounded better than many other products costing 2, 3 and 4 times as much. It's not where it is made but how it is made.

Re: Dussun amps

It works fine on current Krell amps which use 3 different stages of bias.

Re: Dussun amps

Sup, Mike53?
I also have been looking at the Dussun amps and reviews on the internet and am intrigued & skeptical at the same time. I read there was some kind of controversy between Dussun & Red Rose (Mark Levinson Group) but can't really provide any details about that. I googled Red Rose (redrosemusic.com) and found two amps that look identical to the DS-99 & 6Vi, only they called them the Passion & Affirmation, respectively. It turns out these Chinese amps are OEM and their names can be changed & specs even modestly modified by those who sell them under a different name. Nevertheless, I have only read good reviews on the sound quality.

The internal photos of the 6Vi are incredible with the dual-mono circuit layout looking superior to even a Bryston 3B with otherwise matching specs. The $1200 dollar price tag is what bothers me most though (especially considering these beasts weigh roughly 70 lbs). I guess that's the benefits of inexpensive labor.

Since my previous post (my mistake by the way - that was the Music Hall 25.2 series I purchased) I have learned, just as you mentioned, regarding Mark Levinson and other manufacturers buying "off the shelf" items and passing them off as their own. Maybe some of the other reasons these items are less expensive is the fact that functions like phono input and tape out are eliminated. I haven't heard any Dussun or Red Rose devices but the hi-end equipment, from China, that I have heard is impressive.

FWIW, it was Red Rose and Korsun, and the controversy as I understood it was that consumers believed that Red Rose was just re-badging Korsun amps and selling them at incredible markups, but Red Rose was claiming that they were modifying the Korsun amps with better (more expensive) parts, etc.

The original designer (founder?) of Korsun left and started Dussun...

It makes me wonder why the founder of a company, making audiophile gear, would decide to leave and start a new
company...making the same kind of equipment. What's the point. Shows what I know.

Bob Carver? Hmmm, Phase Linear, Carver, Sunfire.....wonder why? And all his "genius" never held the test of time...hocus pocus, out of focus? He defied physics, by trying to convice me, small woofers can be driven by a 2700W amp BUILT IN!! And with a 15A 120 Line cord!!! too bad a 15A 120V ckt can't deliver 2700W !!! But that's the genius of bab Carver ain't it?

Usually it has something to do with a disagreement with a business partner...

This is why I admire guys like Michael Creek. He starts out building a good product line and continues to improve it as technology advances. A good engineer, not some flash-in-the-pan designer.

Re: Dussun amps

That's the Red Rose story, and I think only the overly credulous would accept it. The mod didn't include changing the box and obviously affirmed the basic circuitry design. Given that, why would you even assume any such mods were an improvement rather than just reflecting outmoded design prejudices?

I don't have a problem with someone buying equipment that was designed and manufactured by other parties then placing their name on the device. It's when they claim to have spent endless man hours designing/engineering a piece of equipment putting their own blood, sweat and tears into it.
