Amplifier for my new Focal Sopra no2

Go with Micromega. I have it and run Focal Arias 936 with it -- very nice. Or, go for the Benchmark AHB2, the best amplifier on the planet, bar none!

I don't think that any of the three amplifiers on your list should qualify.

1. Simaudio Moon 600i seems to have adequate THD, but looks really ugly. Also, I found amplifiers without global feedback to be a fad.

2. Naim Supernait 2 ii -- unsatisfying noise floor (See the Stereophile review).

3. Hegel -- some of their amps have bad thermal management (again, see a review in the Stereophile).

I think in recent years various brands have spotted the demand of high quality integrated amp and therefore have launched a lot of good gear. Of course, there are also some products that are below par.  Audition would take a long time.

Besides, proper match among the components is also of utmost important.

I’ve been driving my Sopra2’s with a Simaudio 700i for the past 2 years. It loafs along with around 5 Watts staying in Class A mode except for loud (90+dB) bass peaks in my 15’x24’ room with high ceilings. It has absolutely no problem playing at 100db if I care to listen that loud. 

I haven’t experimented with cables yet. I’m using Discovery Essence and Essential cables and balanced interconnects which improved dynamics over using unbalanced. Highly recommend using balanced if your source permits. 

I auditioned the Sopra’s with Hegel, Naim, and McIntosh integrated amps in addition to the 700i. The Simaudio is very synergistic with the Sopra’s and my choice. It’s magic !!!

Taking more than 2 months, my no2 has arrived. They are beautiful and perfectly fit my living room.

Finally I have Naim 272 and 250DR for their simplicity- 2 boxes only.  I also have set up a NAS for the system.  I know myself that I would seldom play discs when I have a steamer.  So far this is proved correct.  

Sound is is very good and has had met my expectations.  Lovely high (slight too much) and lots of bass (a bit too much and I did some tuning to control it).  Vocal is superb. 

I then have the Naim speaker cables to replace my aged MF.  

Currently doing other tuning like power cords and line filters.  

Sim700 was on my top lists but advices about reselling value in my area stopped me.
