Levinson 333.5 vs. Krell FPB 200, 250, or 300 amp?


We love our Levinson 333.5 amp which drives our Thiel 3.6 speakers. What experiences have you had driving the Thiels with the Krell 200, 250, or 300 series amps vs the Levinson 333.5? What are the basic sonic differences between these amps. Which speakers sound best with these amps? What sonic/design advantages or disadvantages exist between the Krell and Levinson amps?

I lived with a #333 and a pair of Thiel 3.6 for 8 years. Needless to say, I enjoy that combo a lot. I agree with the assessment above. My amp was a dealer demo. Within those 8 years, I had to send it in for capacitor repair twice. According to the repair log, the dealer had sent it in for the same repair once. The last time, I had to pay for it out of pocket.

I had to admit that this last cap change made the combination sound much better. But it cost like $1500. I wasn't ready to pump in that kind of money every 4 or 5 years. So I traded it in for a brand new Pass X350.5.

I was convinced that I would not be able to get much more out of the Thiel 3.6 if I change the amp. It would just be a lateral change. But I was truly amazed when I heard the Pass/Thiel combo.

I had been contemplating about upgrading my speakers for a few years. But after hearing the combo, I was seriously reconsidering that decision. There were just more of everything. I thought there was good bass performance with #333, but Pass took it to another level. The sound is more livier, lots of air, warmer midrange. And the soundstage was much wider and deeper, and more body.

FYI, I ended up selling the Thiel 3.6 and got a pair of Verity Parsifal Encores. The guy got to hear them with my Pass amp, and I spoke to him after he got to hear them at home. He was using them in his garage with some older amp like a Parasound or McCormick or something. But he told me that he really liked the way they sounded with the Pass.

Don't have any experience with KRC-3 or ML 38. But synergy should also be considered.

A friend of mine had compared both X350 and X350.5 side by side, and yes. The X350.5 is much better. All present at that comparison felt that the difference deserved more than a .5 upgrade designation.

Levchappy, another happy GNSC customer here. I am using a Ref level mod ARC LS-25. However, Steve Huntley recommended a quad of Siemens 6922s. But I ended up switching over to Amperex tubes after trying out different combinations. Had the 7308 white labels in there for a while, now running a quad of 6DJ8s.

I was using a stock ARC LS-2B Mk II with my #333.
