Recommend Class a Amp


This past weekend I purchased some Infinity QLS-1 Speakers and the gentlemen I bought them from was powering them with a Krell KSA-250. I was impressed, how the Krell drove those speakers. Most of my amps are tube and I would like to get me a keeper used well thought of class A solid state amp. I would like to stay in the Under thew 3K price range. Look forward to your recommendations.

I've seen them S/H in the US for $5k on ebay and here.

When they first came out this is the price in the US from Stereophile

"Price: $6000/pair. Approximate number of dealers: 20. Warranty: 10 years parts, 5 years labor (US, Canada)."

I think maybe it's because of the Parasound name having too many entry level products.
They are very popular in Australia, they get snapped up s/h as soon as they are listed which is very rarely.
And they will drive anything, as they keep almost doubling they're wattage all the way to 2ohms. Giving an incredible 4,200watts into 1ohm.
And you also have that "magic" switch which gives you a real nice Class A touch to the sound.
And they have the cred of being designed by John Curl, up there with Nelson Pass.
And you guys can pick them up soooo cheap over there.

I heard a pair Dave, driving a pair of Wilson Alexia's there were many other big esoteric amps there also worth $20k+ tubes and S/S and they couldn't come close to what the JC1's could do.

Not only did Stereophile give the Parasound JC1 monoblocks a great rap Tomcy6, but also this site, with lab test also to back them up.

Excuse my ignorance, as I'm from down under (Australia), but why every time I suggest to you American lot, the Parasound JC1 monoblocks I always get a stoney silence?

These John Curl designed beauties are a steel new and s/h, when you live in US. We get charged over $12000K new for them here in Oz, and over $8K second hand. But I've seen them s/h over there for under $4k

Is there a anti highend vendetta against Parasound because they make cheap stuff as well, as these JC1's are firmly placed in the Krell league.

Stereophile boys say you need around 200 watts and good current drive for the babies. That means a big solid state amp if you want the Class A sound as well.
The only one I can think of that would be a reasonable price S/H is a pair of Parasound JC1 monoblocks.
These have the wattage you need and more, but they also have a switch on the back that you can switch to a much higher Class A bias to give you that oh so sweet Class A sound to the upper-mids/highs and a hot heatsinks to boot, but you'll still have the big Class A/B wattage for the bass and lower bass.
And then you can switch it off to lower the bias and power consumption (cooler running) when you just need it for background music.

PS: Zd542, the old fan cooled KSA50 and KSA100 were Class A all the way to clipping. But are under wattage power for these speakers, unless you listen to low to medium levels only and sedate music as well.
