"upgrade" from Cary SLI 80 F1 edition


I've got before very good advice from this forum, so I'll post another question now:
I've got for the past 6 month or so a Cary SLI 80 F1 edition, and I've done some tube rolling , but so far I still think there is something "missing". The sound-stage is quite small and the details are sort of missing sometimes.

I guess I am ready to look for something else, so what else can I get for around 2k that sounds "better" than what I have now. I am looking only at integrated tube amps, but maybe I can be convinced to go separates:)

Thanks a lot for your time and suggestions!

You need to list what speakers you are using (specs if they are little known brand), room size, and music you like including how loud you would like to be able to play the system. Then somebody would be able to offer an informed opinion.
I have a pair of VMPS 626:

Bass: - 16 cm (6") WCF Megawoofer bass, rear reflex loaded
Mid: - rectangular 10 x 20 cm (4 x 8") Neo ribbon, 280 Hz - 6.9 kHz
Treble: - FST, 6.9 kHz - 30 kHz
Impedance & Sensitivity: - 8 Ohm (5.6 min.) 90 dB/1W/1m
Power handling: - 150 W rms /4 Ohms, 20 W min.
Frequency response: - 42 Hz-25 kHz +0/-3 dB
Dimensions & Weight: - 61H x 25W x 33D cm, 18 kg (24"H x 10"W x 13"D, 40 lbs)
Output levels and distortion: - max. 1% THD fullrange / 1 W, max. 110+ dB SPL / 1 m

The room is not very big, but I have no idea about the measurements:)

I listen mostly to jazz,rock fusion and world music at a reasonable level no more than 50% of the max the amp can do.
