Pass Labs users. Next upgrade?

Null 1, I'm useing Analysis Plus Oval 9's speaker cables, M.A.S. Xlr interconnects and Pass Labs supplied power cords. On My TRL Mod SACD player I have a TRL Silver power cord, I forget the model.

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

Ditch the Adcom for about any preamp, but the Pass X-1 or about any of the Audio Reseach preamps would be great choices. I'm sure the 350.5 is better, but the 350 is a very good amp. The Adcom preamp is a major limiting factor in your system.

9rw, Are you talking tube or solid state when recommending Audio Research? There are so many A.R. pre's on the used market. What have you used w/ your X-350? If you are not familiar with my Audio Physic Virgo's they have a similar sound to Magnapan and other Electostatics...(but are not). They just tend to get a little sharp in the highs.
I'm really surprised the Adcom does't match up better with the Pass Amps. I had the X-150 first, with the same results. I believe Wayne Colburn of Pass designed the Adcom 750 and is just a less complicated design than the Pass Aleph P.
