Worth upgrading from Classe cap 101 to cap151 ???

I would buy one Ca-200/201 instead of bi-amping with 2 ca-100/101's. The one 200 series Classe is a much greater sonic improvement alone, over even throwing a Ca-151 into the mix with your current ca-101! I would sell the ca-101 & move up to atleast the 200/300/400 series. Good Luck!!!

The CA-201/301/401 are pure power amplifiers, you'll need a line stage too. (They're 200/300/400 wpc, in case that's not obvious.) My suggestion is that the next step is to buy one of the heavy-duty power amps and use the CP-101 integrated's line stage as a preamp. The step after that would be to upgrade the line stage to something like a CP-45 or CP-65 and move the CA-101 to your office or some other function.

Given the size of the room (30' x 25' x 12' = 9000 cubic feet) you almost certainly need a WHOLE LOT of power on some kinds of music. I'm not into overkill but really I'd say that with that size room it's really going to use it.

Blw,

You know what, I had not even thought about that solution but I think it's a great one. Here is, I think my next scenario as you described.

1-keep integrated for now
2-buy a used power amp, at least the CA201 and have it fed from my integrated (this will lead to choose a proper interconnects but that's another subject all together
3-Since I only have one room that accomodates audio listening, I will eventually sell the cap101 integrated, this will fund the preamp upgrade to 47.5 or 60 or 65.

I am quite conmfortable with this plan. I think you are right , moving from the base line integrated to the top line may not do that much difference. However buy ultimately having let's say the cp47.5 with CA201, I can always upgrade to the CA301 wihtout changing the entire setup again... and most important not go banckrupt!!!

Thanks for your help.
Cheers

Not that you necessarily want to feed the insanity, but here are a couple of more things to think about:

- The CA-200/300/400 family are quite similar to the 201/301/401, but slightly older. They are excellent pieces too, and generally cost somewhat less given their age. I've got a CA-200 and I am quite satisfied. I've heard a few opinions that say that the older family is better than the new one. I don't agree, but it hasn't been just one person who's said this, so obviously there's a mixed opinion out there.

- Apparently it is possible to upgrade a CA-x00 to a CA-x01, for some amount of money. I've just heard about this, and I don't know how much it costs. Might be inexpensive, but then just shipping these puppies isn't that cheap.

- Buy these used. There are always a number of them up for sale here on the 'Gon, and they are excellent value on the used market.

- There's always the Classe Omega family to step up to when this gets out of hand :-)
