Pass Labs users. Next upgrade?

I just upgraded my Amp from a X-150 to an X-350 and love the increased dynamics in my large room. I find them to be similar sounding amps. More fineness, control and dynamics w/ the X-350. My Top end, depending on the recording, can be harsh and fatuging at high listening levels still,(not as bad). Next move, Should I replace my Adcom GFP-750 Pre, the preamp people love to hate (I can only compare it to a Placette Line stage, similar results in my system). I think the Adcom is fine in passive mode and a waste of time in active mode.
Should I spend my dough on a 2.5 or X-1 preamp or go to the X-350.5 Amp upgrade for the most bang for the buck?

The .5 amps are definately an improvement in the Pass line. I also had the adcom and placette preamps. I purchased the x-1 preamp and it was the best move I made. Having the amp and preamp from the same manufacturer should perform a perfect synergy for you. It did me.

350.5 is a awesome sounding Amp. Dont hesitate, go for it!
I have read many threads descibing the 350 or the 250 as being hard in the midrange.
I have also read that the 350.5 version excells in the midrange.
So, I bought one to use with my APL Player direct to the Amp.
Very Mellow sound .Again, awesome Amp!

I also find some recordings a bit harsh.But it is the cd,not the system. I also have some recordings that are fantastic. Have you done anything with your audio room? Bass traps, etc.....Your room is very important also. What kind of power conditioner are you using? That will also take some harshness out. What kind of rack are you using? That can change things even more, Do yo have your speaker wires off the floor? So many things to check before you upgrade.Id still change your preamp, the rest of your system is much better than your preamp.

Null1, I have no room treatments and I don't use a power conditioner. I have my system in the main living area. I would be afraid for my personal safety if I attempted to make my audio presence dominate my wife's decor. I don't have problems intergrating my speakers and subs.. they match seamlessly great bass!... higher mids and highs can be harsh though at higher spl's.
I am an Electrician. At one point in my life, back in the disco era, I ran circuits for Live and D.J. music systems. So I have 2 dedicated 20 amp circuits. One for Amplification and the other for source componets. My neutral and mechanical grounds are not bonded (they are grounded independently)I also use audio quailty outlets( all copper, no brass parts) My Amp circuit is run W/ #10 solid copper wire(less voltage drop during periods of higher demand). They are as quiet as any residental circuits can be
