Upgrade from Pass Labs XA30.8 to X250.8. Worth it?

I am getting ready to make some upgrades to the system. I currently running a DAC into a BAT51SE, then a Pass Labs XA30.8, then finally into Decware DM947 speakers (don't worry if you've never heard of them; not the last word in speakers, but have been doing a solid job for about 5 years now.)

I am contemplating moving up the Pass Labs amplifier line, and the X250.8 looks attractive. I would like to hear more bass authority and definition, but I don't really want to sacrifice the mids and highs of the 30.8. 

I would love to hear some of your impressions of the X250.8, especially if you are able to make some direct comparisons to the XA30.8. I've spoken with both Mark at Reno Hifi, and Kent English of Pass Labs; both are wonderful and informative people. What I am interested in now is the opinions and experiences of end users of either of these amps. 

Thanks!

@david_ten thanks for the report on the exact system I want to upgrade to! 

When I visited Tekton Design, they had their DI’s set up with a tube amp. The logo said “Raven” on the front, and it appeared to be using a pair of EL-34’s for each channel. Maybe 25 watts or so. I didn’t get a close look.

Through the DI’s, that tube amp seemed to have some punch and grunt. I know how those kinds of amps typically sound. They usually sound a bit weak on the low end. I know the XA30.8 is going to make the Double Impacts sing!

@tjassoc I agree with both of you on the power conditioner. It’s definitely on my wish list.

I’m in the middle of a new home build right now. One thing I wanted in the home was dedicated 20A circuits for the stereo. I even increased the amperage of the breaker box just to make sure I’ve got plenty for the future.

there are many Pass dealers that do not use power conditioners, so be careful  before you buy...

I've tried several conditioners on my amplifiers and always preferred them without.  I use dedicated 20A circuits to my JC1's.

Our Sound Application RLS power conditioner feeds our front end components (Meridian 800, 861v8, 621, Oppo 205) via CH Acoustic X20 power cords. This creates a very noticeable improvement.
Our Pass amplifiers are plugged directly into dedicated 20 amp circuits with CH Acoustic X20 power cords. Plugging our Pass amplifiers into our power conditioner has the least improvement and we leave them plugged into their own dedicated 20 amp circuit. This, I believe is because the Pass amplifiers have a very well regulated & filtered power supply,
