Amplifier ideas with KEF Reference 1


I'm thinking about pulling the trigger on a pair of KEF reference 1's for my 10'x14' office (currently LS50's). Current electronic setup is all PS Audio (bhk monoblocks, bhk  signature preamp, directstream dac). Incredible sound, zero complaints other than the fact that the monoblocks run hot. I'm getting cooked so the whole ps audio setup is listed for sale.... Although it just may end up at home for a future 2 channel setup!

So with that background, please share ideas for a high quality system that's cool running. Budget up to $15k. I'll add that I favor the warmer side of the spectrum. I'm a bass player and like tight, fast, deep bass..... Glorious mids, and smooth highs. Current ideas to match with the  KEF Reference 1's include:

1. Bel Canto Black EX (integrated or the separates). My contact says the separates are far superior. I'm concerned this setup is too analytical. Anyone heard them?

2. Bel Canto Ref600m. Keep my directstream dac and bhk signature preamp. Probably more than good for an office!?!

3. Hegel 360 or the new forthcoming monster integrated (590)? They're not too pretty to look at but it seems like I've read about hegel and kef being matched at several audio shows. Is there a hegel house sound particularly with the KEF’s?

4. McIntosh mc611. I'll admit it.... I'm a sucker for the looks of McIntosh plus their easy listenability. I've never had ear fatigue listening to a McIntosh setup. I'd be keeping the directstream dac and bhk signature preamp for this combo. Afraid that is be giving up a lot going from the bhk monoblocks to the McIntosh with similar heat. 

5. Luxman L509x. Brand new. Supposed to be very musical and runs cool. I'd probably run with the directstream dac. 

Your thoughts / ideas are appreciated.... Especially if you've heard the recommendation with KEF reference 1's. It's all about system synergy, right!?!

thank you,
ken

Thanks Everest. What speakers have you found pair best with the Black EX integrated?
Follow up question Everest. You mention needing a really good XLR cable for the Black EX separates. Would a WireWorld Gold Eclipse 7 (XLR) suffice?

Thanks!

@d2girs: I haven't heard the KEF Ref 1's but (1) I have enjoyed my KEF LS50's, (2) they're pretty well reviewed, and (3) I can get a killer price on a new pair. What are you thinking in that price range for bookshelf speakers? I don't want to spend more than $5000. As for Ref 3's, they won't fit in my office.

@jwpstayman: If budget would allow, I'd go for the T+A 3100HV integrated. $17K is my all in amplifier budget. I'd prefer to keep it under $10K.

@drrsutliff: I haven't listened to the Ayre equipment to any great extent. A local dealer pairs it with Magico speakers...the combination was too dry and thin for what sounds good to my ears. Not sure if that's Magico or Ayre....or both!

Thanks for the insight and ideas yyzsb. I'm with you, it's just money..... And considering that I spend more time at the office than home, my office setup should be killer.

I'm thinking whatever I choose needs to have the wife acceptance factor in case it comes home. My wife hated the looks of the wyred, benchmark, McIntosh, and Hegel....the bel canto black ex (integrated or separates) and the Luxman 509x were her favorites so those are my final options. 

Decisions, decisions!!!
I'm thinking it's between the Bel Canto ex black separates or the Bel Canto Black ACI6000 integrated. I don't want to worry about heat in my office again, and my wife approves of the looks (if they migrate home).

Similarly priced.... Can't seem to find anyone who's a/b'd them. Thoughts?
Thanks for everyone's input. I just started a new thread specifically on the aci600 vs Black EX separates..... Hoping to learn more. I'll report back once the system is in place!
@caphill: thanks for the detailed thoughts. My PS Audio Directstream and BHK Signature preamp are sold...BHK monoblocks still up for sale so I'm really thinking integrated or matching pre/dac + power (like bel canto ex).

I also fear purchasing from a manufacturer that's out of business (Classe)..... Of course no guarantees that bel canto's staying around forever. 

Hadn't considered the Devaliet. Might be worth a listen. 

The Linn gear is out of my tax bracket!
Thanks for the naim suggestion caphill and audio doctor. Would you advise this setup over a supernait integrated?
@georgehifi thanks for the additional suggestions... The load plotting analysis is above my pay grade! Do you know if the Gamut runs cool? That's paramount for this office setup. 
@georgehifi  can you tell me how the Bel Canto ACI600 Black graph looks? It's a 25k integrated that's supposed to be very rich sounding. Wondering how the specs look when driving the reference 1's. 

Thanks George!

Thought I’d add a quick update.  

I’ve decided to forget about wife acceptance factor and purchase the amp knowing that it’s staying in the office. 

The Bel Canto looks amazing. I’m fearful of betting on this technology without hearing it in person (no local dealers carry the clack or black ex lines). Thanks to yyzsantabarbara for getting me there!

Hegel is the safe route...was thinking the 360 would work nicely....1. Runs cool 2. Matches well with kef products. The downside - the amp doesn’t support mqa which I really want in my next system.  

I’ve  decided to wait for the upcoming Hegel 590 integrated. Should make the KEF Reference 1’s sing, the newest technology (just being released), should run cool, and the dac supports mqa. Preorder is underway....I’ll be sure to update once it’s received later this year!

Thanks to everybody that chimed in!

Hegel H590 has arrived and is breaking in.

Initial impressions with KEF Reference 1's. Note that it's only been on for about 12 hours.

1. Solid midrange and powerful bass.
2. Streaming tidal and hearing far more depth/detail than ever before.
3. Treble seems a little thin (not harsh) so hoping break in will solve this.

I'm very please thus far and hoping break in will really make the system shine. Stay tuned.

No demo. I figured KEF and Hegel join forces at  so many audio shows that it wouldn't be a system synergy risk.

Small office, no acoustical treatment. Been awhile since I measured but I figure approximately 10'x14'. KEF's bear on IsoAcoustics isolation stands that sit atop a custom standing desk (X-Desk, expensive but very worth it). The desk measures 3.5'x8'. The extra desk width and depth allows the KEF's to be on the desk with no crowding of my workspace  and provides some additional speaker distance/separation.

Bass is incredible. I'm a bass player so I demand tight, fast, deep bass. Very happy thus far.
What is your current setup yyz and what prompted you to go for treatments? Do you listen at low, medium, or high volume? Most of my listening is at low volume but I crank it when no one is around!

I will try to get something posted soon.
