Krell FPB 350Mcx's enough for THIEL 7.2's + CS5i's

I am hoping THIEL owners have some feedback regarding matching Krell Amps with these specific speakers. I have both the 7.2's and the 5i's. The 7.2's are in my primary dedicated listening room, and the 5i's are in the theater. I'd like to buy Mono's, but I am only running across the 350's for sale. I have concerns that these are enough for the low loads presented by the THIEL's. I'd like to have an amp that can handle either speaker so that I can swap them periodically and enjoy the subtle differences. Pre-Amp = Krell KCT, Let me know what experience you have with these speakers and Krell amps.

Hi David,

i suspect the 350mcx will be fine in nearly any but the most extreme scenarios. It has been many years...i have auditioned the 7.2s with Krell KSA 250 and it did clip...but the room was 30x20x with 12-14' ceiling, and the guy was literally playing it at concert levels.

Your Krell 350mcx monos should be substantially more powerful than ksa250, substantially more. so unless you plan on playing them in a barn at concert levels, i think you will be fine.

Hi David,

If you want 450mcx monos, then you're done. Talk to Jack Tozzi at Spearit Sound in MA. They are a Krell dealer (i think), and have a pair of 450mcx monos for $8,500. I have bought 3 big pieces of equipment from Jack over the last 12 years, and people at CJ have the highest regard for him. He is one of the class acts in this business. Please tell him i say hello. If you want an intro, i am happy to email him and cc you. I have done this for a few people. He is great. BTW, i have 0 affiliation with Spearit Sound...i just like to give people referrals when they provide great service.

BTW, i asked Jack about the diff once between the 450mcx and the 750mcx...he said they were bloody close, and it would be up to your speakers to even tell the difference. In your case, i think you will find the 450mcx monos kick some serious a-.

David,

I think if you wish to ensure you've just that extra bit of power, the 450mcx's should be sufficient for anything but the most extreme rooms and volumes (which would probably risk making you permanentenly deaf)

And for those who doubt that it can happen, i know some who wears 2 hearing aids now after an all-day concert-volume session with a pair of Alexandrias...he woke up the next day with very little hearing and it never came back...

Very nice sized room. You should be fine with either set of amps...i would still go for the 450mcx if you have the option... strangely, what i found in my own system is that the better the equipment, the less distortion, while i can play super-loud and not realize it...because the signal is so clean...i also can enjoy at super-low levels and not lose any detail, nor any bass...i've never had this in 20 years. So if u end up with 450mcx, who knows? you might turn it down instead...but always nice to know you can turn it up for theater...and never miss an explosion!

Great stuff, David. It is remarkable what can happen when you put a piece of SOTA equipment into your system. It improves in ways you were not expecting, and it reveals subtle aberrations you did not quite hear were there...but only appreciate after they're gone! Enjoy!

Now what's your next big upgrade? ;)

DAvidstingray...sounds good! What CD player(s) are you considering? I am not an analog guy so unfortunately can only sit on the sidelines there and watch the game.
