I am considering the Krell Showcase 5 the Lexicon 512, Proceed Amp5 or a CJ MF5600 power amp. I will be getting one used on audiogon so I won't have an opportunity to listen to them before I buy. They will be powering my Dynaudio's 3.3, t2.1 and 1.1's. I have a large room 4000sf. Any suggestions? Do I need more power? What about the Aragon 3005 or the Parasound A51. My current amp is an Aragon 4004 for the mains and my Denon 5700 for the rest.
Thanks

Prices?

I think it would be generally more useful if everyone new to these forums is reminded that they are constantly being marketed to and pitched by people who post their affiliations and many others who do not. This is all part of marketing and advertising and you, the consumer, are the targets.

Those 3.3 are pretty power hungry. I read a review of the dynaudio 3.0 which said that the Bryston 4b-ST(300 watts) was clipping. It took the 7b-ST to take care of the 3.0. Now the 3.3 are a little more sensitive at 89 vs 86db, but I am sure they would benefit from at least 200-250 watts. The 7b putts out 500 watts. When you increase the sensitivity by 3dB it will not take as much power. A high quality 250 watt amp is the minimum I would go for.

I agree with Mike, although room size is a factor that may mitigate somewhat. All of the choices above are good, clean neutral amps except the cj (not a slam but even their solid state amps are voiced a little on the warm side). Given they're all manufacturers with respectable pedigrees, I'd go for the maximum wattage if it were my choice.

Cheers,
Philip Brandes

Of the ones you listed the Aragon 3005 (300X5) or the Parasound A51(250X5) would most likley be fine power wise. Also concider that they have a nominal impdence of 4ohms. They can also dip down to 3.2ohms and have a long term power rating of >300 watts. Sound wise you would have to listen for yourself.

I have a large room to fill about 3500cf opening on one side to a 2500cf kitchen. I think Mike and Philip are correct.

I have heard the post Harman Aragons are no match for the older 4004's and 8008's. I am going to keep a lookout for a 8008x3 or a Krell 3250. I think the Aragon costs about $1,500 and double that for the Krell.

The new Aragon 200x series amps are rebadged Acurus amps. The 300x series are somewhere between Acurus and classic Aragon. The Aragon 8008x3 usually goes for 1000-1150.

Yes, I would like to get a 8008x3. If it sounds like my 4004 I would be very happy

Actually, the 300x series is just a more powerful 200x, still Acurus, and the same exact design. Just more power. I'd look for an 8008x3. I had one of these for a few months in my system. It is a beautiful amp.

If it's not worth waiting until the last minute to do, then it's not worth doing.

The Argon or Krell 3250 should be fine.

Just my luck a 8008x3 just went up for sale on Audiogon, great price but they won't ship.

There *is* one more choice if you want to go 3 channel: Proceed HPA-3. I don't need as much power as you do, and I have a 7.1 system set up around a Proceed BPA 2 and an AMP 5. The best amplification I've had in my system. Very smooth presentation.

I will add the HPA to my list, thanks

I have the Dynaudio Contour 3.3s and a T2.1 center with the Proceed AMP5. I have no problem with sound levels. My room is a great room that has 6000 cu ft and is open to the kitchen, den, and hall. Total volume is much higher than 6000 cu ft. The Dynaudios are 4 ohm, and the AMP5 doubles at 4 ohms. No problem with compression of clipping...joe
