Preamp possibles for system...


I am currently using a Belles 21A auricap but have been itching to try something else for possible system improvements. The amp is a T-hold S/500 ll with an Arcam CD23 and Polk SDA-2's with RDO-194 tweets. All IC's/PC's are Morrow Level 3/4. My 22'x35' listening environment is slightly harsh with wood floors and a fair amount of glass. Musical taste is quite varied at moderate volumes.

In general, I feel the base or low level frequencies are a bit forward but not crisply defined. Also the high frquencies seem somewhat constrained or maybe rolling off early...using others terminology I have read. Almost as if the singers are behind the band. Not always, but on enough recording's I notice it.

My previous amp was a Nak 7. Everything else staying the same, I recently switched to the T-hold S/500. I literally would have wrote an exact opposit review of the systems traits critiquing it with the Nak. I was certainly surprised...in a VERY good way.

I have read that the T-hold amps liked certain pre's. Here is a list I have gleaned from some research. I have not seen all of these available, so some maybe out of the question. I would be gratefull for any input to try and target my continued refinement.

Aestetic Calypso
Audio research LS25 mk1 or 2

Would you consider replacing your Arcam player? CD players have significantly improved over the last 10 years. Since you have vintage gear is everything running to spec?
Dayglow...Yes, I would consider replacing the CDP. I know the amplifier is running to spec as it was just recently checked out. I am currently getting ready to have the crossovers reworked on the Polks.

Jmcgrogan2...No particular reason on not having the T2 on the radar. Can't say that I have ever stumbled across one used on the forums or read them discussed much in my research. Certainly I do not put my entire opinion on that but just something I have not been exposed to.

I appreciate the opinions to help me pick a direction for funds to be used.
Sounds logical. Here is a few CDP's I have seen reference to with Pass gear I think would be in my budget. I think most of these are still near the ten year old mark. Would they be a marked improvement over the CD23?

Ayre Cx-7
Accuphase 65, 67
Arcam 37
Marantz 7si
