Best speakers for PASS Aleph and SONY CD?

System:

Source: SONY SCD-XA777ES

Pre-amplifier: PASS Aleph P
Power amp 1: PASS Aleph 3 (HF)
Power amp 2: PASS Aleph 0s (LF)

Observations:
- The amps would be used in bi-amp configuration. Both have 20dB gain.
- The Aleph 0s has a lot of current and drives well hard difficult woofers.
- Room is small-mid sized, but plan to move to larger one in two years. So, the speakers would have to result well in small-mid to mid-large rooms.
- A sub-woofer is not in consideration.
- Music: Jazz (70%) and rock (30%).

Suggestions? Thank you!
