Parasound JC 1 or Musical Fidelity KW 550?

Response to Mribob
I had a dealer demo an a/b comparison for me of the Parasound vs the MBL 8011's...it wasn't close; the mbl's were much tighter; cleaner; smoother; and richer than the Parasound...and run a lot cooler...was not impressed with the Parasound...this was on same cables and speakers; we just switched out at same listening session the different amps; on same music source...it was very revealing...and they are similiar in price...just my two cents.

The MBLs are $7150 PER Mono-block, so they are 2x the price.

Another vote for the JC1's, I found them to be very good and mate very well with the SF line 2SE+ I had...

I have to agree w/Peter about the JC1 and lack of magic,found then to be flat and uninvolving .Ive heard of several users with build issues,plus they get hot as hell..I would recommend a larger Pass X.5 or the Mac 501 monos just to name a couple to drive those sometimes bright 802 speakers

Thank you everyone for all your inputs.
I thinking about getting a used Pass Lab 350 or 250 or may be the newer .5 series. Is Pass lab Amps durable/reliable? Do they have any issues? I know it runs in Class A. Does it run very hot? thanks

IMO ...Again ,I cant stress enough about factory warranty..I bought a new X.5 amp and it went to factory 3 times in a 5 month period..Was bad out of the crate,had distortion in one channel,and no it wasnt something I did on my end..It was repaired correctly the 3rd time but still it cost me over $125 to ship to them (3 times)plus the down time in my system.I moved away from Pass simply because I lost faith in their product.Im sure there are more with postive comments about Pass and a few like myself with a bad taste.I would never buy an older 250 or 350 without having the current owner send it to the factory and have them run it through the paces(cost on the seller of course),I would contact Pass and verify the process before laying down cash.Buying something on the used market is risky,better through this site but still risky.Thats just my mindset on used gear.Good luck in your purchase
