Bryston 4B Cubed vs Hegel H360 vs Benchmark AHB2

I am likely going to get the KEF Reference 1 for my office at the end of this month. I was trying to convince myself to get something else but I always came back to the KEF Ref 1 for many factors, such as sound, cost, size, ease of setup.

I think the KEF Ref 1 speakers can use a lot of power even though they are rated at 50-200 watts at 8 ohms. My setup in the office will require a few digital inputs  and 1 or 2 analog inputs. 

I have narrowed down my list to the following electronics:

1) Benchmark DAC3 + AHB2 amp(s), I have not heard the AHB2 amp but did own the DAC2 for years and liked it a lot. Only issue with this setup is that I will likely need to get 2 AHB2 amps to get over 100 watts for the Ref 1's.  Anybody with these amps think I need 2 of them for the KEF Ref 1's in an office? I sometimes play music loud but not for long while I work. I would buy Benchmark as new gear.

2) The Bryston 4B Cubed along with the Bryston pre-amp with integrated DAC option. I owned older Bryston gear in the past and one complaint I had was a slightly smaller sound stage. I would buy the Bryston gear on the used market.

3) The Hegel H360. I heard this unit playing KEF Blade 2 at a show and I was pleased with the sound. I loved the sound of the Blades but I may be giving too much credit for the sound that day to the Hegel. Whatever, the case it was an enjoyable experience. I could go used or new with this gear. My concern about Hegel is repair work and reliability. I have never owned Hegel gear but I have read some rants here about Hegel customer service. BTW - Is there a new H390 in the horizon?

All of my choices are in the detail oriented sound camp. This is fine for my office system since I am getting a warmer sounding system later on for the living room. Some variety in systems will keep things interesting.

Anybody have any feedback on the 3 brands I have listed and the concerns I have for each.
