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

I’ve decided to wait for the upcoming Hegel 590 integrated.


This looks better to drive those Kef’s low impedance/-phase angle with in the bass, good choice, and it’s linear not Class-D always better to me so far ("the future is not set").
More output devices and bigger power supply, bodes for better current delivery than the H360 can give, and hopefully will drive that bass of the Kef’s without becoming a bit of a tone control.

"The Hegal H590’s class A/B output is executed by 12 transistors per channel (4 more than the H360) to deliver a very specific 301wpc into 8 Ohms. Hegel’s feed-forward loop wrestles distortion in real time. The power supply inside the H590 is twice the size of that found in the H360"

Ken, you should listen to the Bel Canto Black gear it does seem very interesting, personally we aren't so keen on very expensive amplifiers that digitize analog and don't play DSD but the overall reviews and features are excellent, we may contact Bel Canto and see about becoming a dealer for the Black gear as it is perfect NYC rig. 

You may also want to check out the new Anthem STR gear which is less expensive and sounds extremely good, The amp and preamp/dac are $10k and offer the superb Anthem room correction system which may make an extraordinary difference in a small room with the Kef Ref 1. Anthem pictures the gear stacked so you may be able to save space that way. 

If you are ever on the East Coast for business, we have the Ref 1 in a room with many superb contentenders including the Naim Nova which is excellent with the Ref 1, we also have the Naim 272/250Dr which sound mindblowing on the Ref 1, we also have the Anthem Separates, and the T+A gear, we also have the Micromega M150 has room correction.

As much as I said I was bowing out, I just want to chime in quick and thank audiotroy for being open minded about Bel Canto Black. I promise that you will not hear the digitization of analogue at all and their phono stage built in is very good as well. Bel Canto has displayed their Black gear with analogue front ends plenty of times and have always had great press about the sound quality. Bel Canto will do DSD64, but not natively. They opted for the MQA route and it does full MQA processing. You should definitely consider it for NYC. I'm not sure if there is a Bel Canto dealer in New York or not. I think it would be great for that market. Cheers.

Everest they chose to do convert DSD to PCM as part of their design. Not necessarily the best way to really play DSD and just because you do MQA doesnt' mean you can't play those files back at Quad Rate DSD we do exactly that on our $35k Light Hamonic Davinci and boy does it beat standard 24/192k MQA files. 

This is one of the reasons why we thiink you really didn't experience the T+A Dac 8 DSD the absolute magic with that Dac is running everything as Quad rate DSD, a DAC like the DAC 8 gives the listener total control to play back DSD as DSD or PCM as PCM.

Personally never have been too keen on digitizing vinyl playback.

We will see about getting a sample of the Black EX as this piece might be as stated the perfect NYC apartment rig. We first tried that with Devialet and the Devialet although very impressive in many areas, never was musical enough for us to fall in love with the Devialet sound.

The new Hegel might also be a very nice contender. We have so far found real magic with the KEF's with the Naim and T+A gear. 

Everest we have one up on you on that one we are one of the very few dealers in the country to display the entire KEF line, we have Ref 1, Ref 3, Ref 5, Blades, and our Ref 3 are in a full Atmos KEF theater which rocks. 

We know that you didn't carry the higher end T+A gear which is a pitty the HV gear is amazing you might just prefer it over the Black, however, the simplicity of the Black might be very appealing to some people.
