Hmmmm.. . well the obvious answer is get in line for a new Torii. With the CSP2 and the Torii you should be right there. The 84C does have its limitations. . . .

Others may have different advice, but in my opinion, with the CSP2 not doing it for you, you need to have the heavy Decware hitter, the Mk III, in the system.  It will give you the Decware sound, and much more power.

I'm now redoing my zen vinyl playback; I switched back to decware speakers, added decware IC's and speaker cables, and added a solid state Dyna rebuild by Van Alstine (pat-5)..then matched decware integrated with decware preamp plus Cary/aes phono preamp..my only question now is what speakers match well with the integrated...am I right that 8 ohm is better than 4 0hm single-drivers??  I have 8 ohm boston acoustics cr9's that sound pretty good but also can match/try 4 ohm triangle titus...zen redo now sounds great with decware speakers and solid state amp....more slam..any addition ideas welcomed...ps..everything sounded better after I played new zen hookup for 45 minutes and everything warmed up...I expect more improvement when cables/IC's improve with use...haven't used them in 2 years although they are used!
