Pass Labs XA30.8


Do you think Pass Labs XA30.8 has enough power to drive 86 dBL Dynaudio focus 380 speaker well? My room size is 23'x18'x8' and I sit about 8' away from the speakers. Usual loudness is about 50 to 67 dBL when measured with noise meter app using my phone.

Also, what sonic improvement will I hear going from Bryston 4B Cube to XA30.8? 

I can't imagine you'd have any troubles driving those speakers with the XA30.8, especially at the listening levels that you indicated you prefer.  People seem to forget that doubling your wattage only increases to volume by 3dB.

Is Audio magic mini reference 2 conditioner much better than Audioquest Niagara 1000? I was also considering PS Audio P12 power generator? Which would be most effective to create that 3D effect? 


Pass Labs XA30.8 will not do it and Dynaudio focus 380 need more power to shine especially in the bass frequency as it will go below 4 ohm.

I'd recommed Luxman M-700u as it can give 120 W/8Ω to up to 840 W/1Ω instantaneously exploits the full potential of speaker characteristics under any load conditions.
Have you heard an xa30.8!? It is far more powerful than 30w. It is rated at over 100w a/b into 8 ohms. It can easily drive a 4ohm load.
