Pass labs krell parasound amps

i own the Krell Illusion pre along with the Krell Duo 300xd with the ibias tech

and the fans in the back never come on no matter how hard i am driving them

I usually listen to them at low volume with great reasults as they run Class A up trough there power curve due to the ibias tech I also use all Sil-tech cables for my interconnects and speakers I would think if you found a used Duo 300xd i would not pass it up 

All of the amps that you and others have mentioned are great choices. I’ve had Pass Labs and now I’m using Krell. The Krell that I’m currently using is the Evolution 302e. It sounds very different to the previous Krell’s, even different than the non “e” evo’s, and closer to the Pass X series that I’ve owned. Which is better? That’s a matter of taste as they’re all extremely capable amps. The newer Bryston amps like the 4B SST3 are also very good. I was actually surprised at how good it sounded as I had owned an SST which wasn’t as good as my old Aragon 4004mkii. You get that awesome Bryston warranty as well. I’ve seen lots of love for Coda but have yet to listen to one. I also have a First Watt F3 which is excellent but it tends to run out of juice (18w iirc) when I get the urge to rock out 

totally subjective but

when I look at Krell, i always think that they made it look so ugly ON PURPOSE  to challenge their buyers to get over the aesthetics and just focus on the sound.

It must sound incredible if people still buy them despite their looks. 

I'm using a Coda #8 V1. I was using it with a Holo Audio Serene KTE preamp with excellent results but now have it paired with a new BAT VK-80 Tube preamp. It's a magical pairing especially with my Magnepan speakers! The V1 amp has heatsinks for a 400-watt amp (Very cool running) but is a 150-watt Class A/B with the first 18 watts Class A and a 10-year warranty and 5-year transferable warranty. 40 output transistors, 150 AMPS peak current and a massive 3Kva toroidal transformer. The amplifier can be upgraded by Coda free of charge (Minus shipping costs) to a V2 at 250 watts into 8 ohms or a V3, 400 watts into 8 ohms. All these power levels Double into 4 ohms. Highly recommended amp.

@gano Krell were first to introduce beauty in the form of blue power-on LEDs.  My KSA-80 with its massive external fins protruding way beyond the facia must be the ugliest of all!  While it is rated at only 80-Watts into eight Ohms, this doubles for 4 Ohms and again for 2 Ohms where it is rated 320 Watts RMS per channel.  For decades I used it to power Quad ESL-63 and ESL-2509 electrostatics which protect themselves from over-high input voltages by presenting as a short-circuit to the amplifier.  I tried powering them with a Luxman valve amp, but it put out high voltage spikes when switching on, which caused the speakers to clamp.  Could never get the amp and the speakers to be powered up at the same time!  No such issue with the Krell.
