Thiel Owners

Hi All,

This may be a dumb question based on earlier responses to my post about treble glare at high volumes.

Is it possible to improve the treble sound by using  an amplifier that stays in Class A longer?

My Coda CS stays in Class A for the first ten watts. If another amp stayed in class A, say, for 20 watts, could it sound better in the treble at high volumes?

Does anyone possible know the bias for a McCormack DNA-500 amp?

Thanks for the help!

Well after listening to the Pass 150.8 on my Thiel 2.4s all weekend it still seems true that the Pass is a little thick in the lower midband (kinda like me) during orchestral swells.  There's that little bit of homogenization there but on everything else it seems to be a great combo.  On vocals in particular its an amazing combo.  So I'll probably still try an ARC amp this week but I'm less inclined to try the expensive Ayre monoblocks.  I'll report more later...stay tuned.  And yes I was tempted to try the new PS Audio amp but only the stereo amp is really within my budget and its a similar topology to the Aesthetix Atlas which I already have and like "okay" but that one is probably going to get sold.

PW - I am all ears for as much detail as you care to share regarding your auditioning. The Crossover Upgrade Project is addressing all aspects of crossover performance. Jim's CS2.4 Signature Edition significantly upgraded tweeter feed capacitors, which certainly affect the entire midrange clarity. Our work will replace those ClarityCap SAs (then state of their art) with CSAs which are considered significantly better. Additionally we will be CSAing the upper end of the woofer, which certainly addresses the lower mid-band (I can also afford to lighten mine).
Update: I now have in-house all the ClarityCap CSAs and CMRs along with RTX and Cornell Dubilier styrene bypasses and 4-9s wire and foil coils to build out the PowerPoint, CS2 2 and CS2.4 prototype crossovers. My test mules are my PowerPoints and CS2 2s before we take on beetlemania's CS2.4s. I have two levels of upgrade specified for each of those first two products.

I am listening closely to the collective listening experience of the various forums, to augment reviewers and my personal experience. All are welcome to chime in regarding their perceptions, especially of two-series products. My available time is a distinct limitation, but my interest in the Upgrade Project continues to grow.
