Which integrated amp?

• Powerful- it has plenty to really make my power hungry Dynaudio C1’s sound huge. This amp has 100,000 u/f capacitance, along with a massive power supply.
• Really good at lower volumes as well. It has been described as a “velvet hammer”. I wouldn’t say tube-like necessarily, but it gives the sense of smoothness that is rare with a high- powered integrated.
• Well built 60 lb beast
• Versatile

• Mine has the phono stage, which is just OK (I upgraded to a Manley Steelhead). 
• XLR inputs are NOT balanced inputs, they are there for convenience if you happen to own gear/ cables that use them.
  
• Non-transferable warranty. I know, most aren’t, but my power supply developed a hum audible through the speakers and I had to return it for service. Pretty pricey due to the weight  and shipping both ways.

Sorry, I usually don't participate in the forums. Here is some additional info on the SA integrated, specifically the 600i.

Dual mono, 125W into 8ohms, doubles into a 4 ohm load. If you take a look at images you'll see that it's basically 2 mono amps in a single housing! https://www.bing.com/images/search?view=detailV2&ccid=sv68ItUi&id=E3EC2937ED4B29AF32AD501403...

Has a balanced input, 4 SE inputs and pre-outs that can be configured as variable or fixed. Also has the M-eVOL2 volume control with 530 steps of loudness. 

I'm currently running a pair of Dyaudio Focus 380's, and doesn't run out of power even at house rocking levels.

I'm not a sales guy, but since I've upgraded to the SA I've been very pleased! I've compared this to the Hegel 360 and in the system the SA bested the Hegel. I've not heard the others in your list, but have seen a lot of good reviews on the Modwright integrated.

The below is a link to a review of both the 600 and 700i amps.http://www.tonepublications.com/comparo/simaudio-600i-vs-700i-and-the-i7-too/

Enjoy the journey!
