Best SS amp choice for Zu Omen


I am considering 3 inexpensive amps to drive my recently obtained Zu Omens. My NAD c326Bee is a little warm for my taste and have decided use it for a second system in my bedroom. These 3 amps I can get between $600-$800 Musical Fidelity m2si, Music Hall a70.2, or a Naim Nait 5si. In the near future I am definitely wanting tubes, but I need a little time to study up on the matter.

purchased a MF from upscale a few months back ..no problems at all with upscale.
I also have the Zu DWs ..it was a good match and sounded fine..that said  had an intermittent issue with the MF..occasionally on first start the volume would wack out...one time the speakers were vibrating pretty noticable
the only solution I found was to turn the voldown after everty use and turn on /off repeat when starting up..tried a diff remote ..(the one supplied is cheap)..same issue intermittently.....I just got the Kinki EX  amp so I put the MF on the shelf
Does anyone know what the warranty for a new Musical Fidelity Amplifier? I haven't been able to find it on their site.
Good question.  Pro-ject purchased MF a few months back.  I believe they said they would honor the MFs warranty.  I would reach out to Pro-ject/ Sumiko here in the states.

I know you specifically asked for SS amp options, actually I think you meant integrated amps, but if you’re flexible, there’s a Rogue Sphinx hybrid integrated currently for sale and that should be another decent option. Not mine.
Rich, thanks for your response. I've narrowed my choice of integrated's to two. A Musical Fidelity 2si  from Upscale for 599.00 or a Music Hall a70.2 demo from a local dealer for 750.00. Ever heard a Music Hall.. any good? Will use to power Epos Epic 2 and Zu Omen until I find a tube amp for the Zu's.
