Best sounding Krell ?

Stevecham: Comparing the KAV-400xi to the KCT/FPB-400cx is silly...come on now...the Krell Employees and Dealers that I know, wouldn't even go there. The KAV-400xi is an OK Int. Amp., it does not represent the current "state-of-the-art for solid state amplification, and it is simply not in the same league as Krell's previous Class A and current Evolution Series Components. Anybody who doubts that, could simply walk into any Krell Dealer in the Country and hear it for themselves (every Dealer has a 400xi somewhere in the building). The KAV-400xi sounds good on its own, but when you run it against tier-one seperates, including Krell's own, it sounds like a step above a Receiver. I also ran it against another popular Int. Amp. - BAT's VK-300xSE, and again no A/B comparison was needed, the BAT was sonically a step away from the Krell in all areas, except maybe for power - which in any case, was close.

This is a ridiculous apples to oranges comparison, and it is not fair to our fellow Audiogoneers, that do not have access to a Krell Dealer to Demo. the 400xi for themselves, to see exactly where it lies sonically in the HiFi Food Chain, which is clearly; "entry-level". It's threads like this that contribute to so many people ending-up disappointed, after purchasing the 400xi, thinking that they were buying a bookshelf version of Krell's Evolution seperates.

Again, for the record, the KAV-400xi is a nice-sounding and fairly-powerful Int. Amp., but it is not a giant killer, or a replacement for high-powered seperates, believe me, I had one in my Home for years, as an inexpensive back-up while I was auditioning Preamps. & Amps. - with that said, for less then $3K new, I do feel that the KAV-400xi is among the best in "its" class.

I never stated nor implied it was a giant killer, and yes I can tell the difference sonically in a heartbeat when compared directly to the higher end electronics of my main system, but it is not that huge a leap downscale as you have indicated in the quote. But it ain't dead; certianly those words were a bit over the top.

And it is not merely a step above a receiver (I have owned several so-called high power units through the years) but instead provides some very real musical magic in terms of imaging, soundstage and naturalness of timbre. It is a fine piece of equipment, regardless of price point. Sure the KCT/400cx is clearly in another league, and I never implied otherwise, nor do I plan to ever part with that fine combo, but the 400xi is clearly cut from the same cloth and kudos to DanD for retaining the sonic attributes of his higher level gear at a relatively afforable price. Plus it is certainly a better integrated amp than the Musical Fidelity A5 that it replaces, and I say that at my own peril as I prepare to offer that unit for sale on the 'gon.

In a properly set up system the 400xi is a giant killer...period! Not with the stock PC or average cables or a mismatched front end, but with the SACD standard V3 and the tweaks I mentioned, it is far more engaging than almost anything alse I've owned. The 400xi is essentially the purest version of Danny Boys best efforts...simplify my friend and it will set you free. Component matching, room acoustics and extensive set up are required for best results, regardless of the gear! What I'm saying is that if you want a simple and purely musical sound without the added dollars and headaches involved with making various seperates work with each other, get the 400xi and build something wonderfull. Other than that, get a used KCT and a 400cx..it don't get any better in krell land!

I would vote the 400cx. I dont own this amp but I am seriously considering . I am shopping for a krell in this price range and have done extensive research and the 400cx is the amp that I am gravitating towards. I am thinking cast system eventual and this would start me down that road. This brings me to my question. I want to know if in a bi amp system (vertical bi-amp) WITH IDENTICAL AMPS COULD LEFT CHANNEL FROM EITHER AMP BE CONNECTED DIRECTLY TO THE BASS WOOFER OF AN APOGEE SPKR AND THE RIGHT CHANNEL FROM EITHER AMP CONNECTED TO MRTW BY WAY OF THE TRANSFORMER? This may sound like a no brainer, but I am not knowledgeable enough to know the answer. thanks

I would consult with Krell's technical division if you are seriously thinking about this idea. The Krell amps are push/pull - (neg/pos)...sending one channel to half of a speaker and the other channel to the other half would make no sense and be playing two different signals i.e..woofers playing right ch. info and mrtw's playing left ch. information! Makes no sense...maybe one amp for the bass/L/R and another for the mrtw sections L/R, but a 400cx will drive just about anything out there. Remember, Krell amps sound their best when being driven hard..even Jonathan Valin from absolute sound noticed this when reviewing the Krell KCT and 750mcx's.
