Lively, fast & open sounding integrated under 3k?


My speakers are 89db 2 way monitors with a very warm sound. Minimum impedance 3.5 ohm
large Room, low level listening 

My goals
no.1
excellent immediacy, speed & timing (dont recommend naim, very unnatural forced sound)

no2
forward soundstage (begins at the listening position and extends beyond the speakers)

No3.
Body without warmth

no4.
small in size if possible, but no class D, doubles into 4 ohms, Good at low volumes
new or used.

possible candidates from reading reviews

The Hegel seems a bit too warm, dense and overdamped - not lively.

MF sounds unnatural to me.

I try to find a belles aria.
Yes, when JC1 is switched into high bias mode, it becomes very warm.
Not to me they become invisible like the speakers have left the room, and the music just washes over you in a 3D sound stage, that you swear you can get up and walk into. 
And I've built many, some very big ones over the last 30 years, even a self contained 120w-8ohm pure class-A water cooled one that could double down to 2ohm, that was two man lift, the size of a coffee table.

MF sounds unnatural to me.

+1 They MF sound, are even more cooler, etched, than the JC1’s in low bias mode.
Never like them, definitely a MF house sound (very high gain used?), even their old little A1, A100 so called "Class-A’s" had the same sound, which btw were lucky to be measured to be even 10w of Class-A
