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.

A true differential balanced unit will have to double the number of parts in some stages.

This is not correct. It is true of *balanced* if not differential, but if *balanced differential* the parts count is less than double.
The Dunlavy Contata's finally arrived and are now mated with the Bryston cdp, T-hold S500II and Belles 21A pre. Aside from the larger and more powerfull presence the Dunlavy's provide, much of my earlier tonal critiquing generally applies. I would like a crisper, tighter control of the lower frequencies and bass. In general, the mid and upper ranges are pleasing though seem to lack an overall clarity or depth to the finer details. Reading others use the phrase "a veil has been lifted", seems to best describe what I am hopefull of.

The point was offered up that I may be over-amped. I never thought of that possible and am unsure how to gauge that.

Perusing the archives and available used items, I have continued to update a list of possibles for experimenting. My budget would preferably be under $3K. Thanks for any input.

I can't help but wonder if your problems might be more room related than equipment related.
Thanks Unsound...Good possibility. I assume you base that on me mentioning how bright or harsh some of the rooms large material surfaces are. The low frequencies negative affects on "everything" I know are real. It definately sound better at low to moderate volume levels.

Putting the systems performance aside, I do not feel the Belles is a good match. The gain is obviously quite high as I rarely am above 9:00 o'clock on the volume and very loud is often near 10:00 o'clock. Makes for difficult fine tuning. It also is Black and I want something more closely matching the other components...nitpicky I know.

I am noticing a tweeter issue on one of the Dunlavy's. I am hoping I can find a worthy replacement. The more I am working my way through my music collection the more impressed I am.
Well I did some more testing with impromptu room treatments and speaker placement. My conclusion is that on low volumes the bass seems to be fairly controlled. As the volume goes up the low frequencies start/can get muddy, for lack of a better term. I am really itching to compare the Belles directly against another pre. It is either that or start purchasing tubes for trials though aesthetically the piece is also off.

The Cantata's tweeters were replaced with ScanSpeak D2606/9220. Madisound recomended them as direct replacements for the original Vifa D27TG-35. They are made in Denmark and were exact copies. I am quite happy with thier sound even being fresh.
