Pass Labs XA30.8


All, 

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? 

Thanks.

Elizabeth, that's an interesting point you mentioned about AC receptacles. My dealer has been telling me that I should replace my $1 receptacles with Audioquest Edison. Perhaps I should change that first and see what differences it makes to my system before changing my current amp.

About my setup: I use AudioQuest Niagara 1000 power conditioner. From the wall AC to Niagara, I use AQ Thunder PC. My digital front end / preamp is Moon 390. I use Zu Event I PC for the 390 and 4B Cube. XLR IC is Siltect 550i. My speaker cable is AQ Rocket 88. My room is treated with 10 HFTs.

I honestly am happy with my current setup, but the improvement I am looking for is more holographic sound, stable imaging, depth, and tonal accuracy. I am not even sure if changing the amp will give me that or not, but by reading reviews on the Pass amp, I get the sense that it exhibits those sonic characters that I am looking for better than the Bryston amp.

Paneri a more holographic soundstage will be accomplished by making a few changes:

1: Upgrade from the Niagra 1000 to an Audio Magic power conditioner 
2: Upgrade from the Rocket 88 not good enough for the system
3: Use footers undeneath the preamp and amp, Critical Mass are expensive but amazing.
4: Isoacoustics footers under the speakers will make a very noticable improvement.

After those tweeks then I might look at an improved amplifier.

I have speaker spike feets from Herbie. They made noticeable improvement over the stock penny feets. I suppose Isoacoustics feets are better... but more money too.

I use an Ikea TV furniture for now, why would amp blocks make any difference, does seismic vibration affect electronics? Can I use something like this instead?

@panerai557 specifically with respect to your question on the difference in sound character between your existing Bryston 4B3 and a Pass XA30.8, the design goals of the two companies are different. If you like the way Bryston sounds, you may not like the way Pass sounds. And vice versa. I think it would be misleading to say going from one to the other gets you more of something, or is a general improvement, as opposed to what I would instead describe as changing the direction of your sound.
