I have a pair of RF-7's with Dean Wescott crossover modification and I want to buy an amplifier for 2 channel listening.

I am currently using A Classé CAV-150 150wpc for home theater 6 channels and I have a chance to buy a

1. KRELL KSA 80B   80 wpc pure class "A"

2. Classé CA-200 200 wpc class "AB"

3. Parasound Halo A21 200 wpc 8 wpc class A and the rest AB.

Please recommend between these three amplifiers.

Thanks.

Wow, what a choice! I won't be of any help unfortunantly since I've never auditioned any of those amps, but I'm sure you wouldn't go wrong with any one of 'em.

I noticed you made the point of adding what amplifier class these amps run on...I assume class-A operation is important to you(?); if so, the Krell may be your first choice. I don't know about SS amps, but I can tell you class-A operation with a low powered, single-ended, zero negative feedback vacuum tube amp is especially sweet sounding with Klipsch horn speakers.

Regardless, there are endless possibilities with your Dean-modded RF-7s since they're so efficient and an easy load with whatever amplifier you decide to use, so I don't think you'd go wrong with any amp from your above choices. Hopefully, someone with the proper experience who knows those amps will be able to better serve you than I have.

Good luck with whatever choice you make!

I'd take the Parasound,only because I know they make outstanding amps for the money.I had a lesser Parasound,still one of the best amps ever hooked to my 7s,something magical after it warmed up.

Did you take the Aragon off the back channels and try it on the RF-7's? Just curious.

Haven't heard a Krell on anything in 15 years -- but I do know Parasound and Klipsch is supposed to be a killer match.

 HI Dean:

Yes, I put the Aragon 8002 up front bi-wired and I just couldn't quite get that musical sound I desire for stereo listening.

I guess I am an AUDIOHOLIC. LOL. Someone I work with recommended these amps and I'd like advice.

My sincere thanks to all of you. 

 I can get a Parasound HCA-3500 350 wpc for $1100. What do you guys think betwwen this amp and the Halo a21 for $1200

 I have decided on the Halo A21 for the fronts. I bought one on Audiogon and expect delivery sometime this week.

 Sold the Halo A-21 and purchase a 1985 Threshold S/300. I sent it to Jon Soderber for upgrades. He replaced the Capacitors, installed Cardas binding posts and a Ixys fast recovery diode. This amplifier in really nice with my Dean Wescott modified RF-7. 

The Krell and the Classe amps are in a different league than the Parasound.  What preamp are you using? 

I would guess that the Classe is a better match to the RF7's as Krell can have an edgy top end with the wrong speakers and Klispch can be harsh with the wrong amp, Classe is suposed to be smoother. 

 I've never heard any of the amps in question but I tell ya when I had Dean modified 7's the best sound I got of them was with my QSC amp below...cheap too.
