SS. Amp to go well with Aesthetix Calypso Preamp.

Tvad
according to Sterophile review on the Calypso the the input impedance 80k ohms balanced, and 40k ohms single ended. the output impedance is 600 ohms balanced,and 300ohms single ended.

Thanks

Those are pretty good nominal output impedance specifications, but nominal output impedance can be misleading.

Check the measurements section of the Stereophile review and see if Atkinson mentions significant rises in the output impedance into lower loads. This is a characteristic of tube preamps. He would have mentioned this if he observed it, and if so, it would suggest possible bass roll-off if used with low impedance SS amps (say below 20k-25k). Atkinson will often be specific about this match.

Thank You for your support. I will read over the review.

The Theta Dreadnaught amplifier works very well with the Calypso. If you can find a 2-channel one it should fit your budget.

Here is an old thread. http://forum.audiogon.com/cgi-bin/fr.pl?aamps&1141898495&read&keyw&zzaesthetix In it it is claimed that Jim at Aesthetix at one time did use Ayre equipment in conjunction with his own. There is an old thread about a compatibility problem with some of the older stuff, and then Charles Hansen (Ayre) chimes in and explains an old bug that has been eliminated. Anyway Ayre might end up on your short list, in which case this old thread may prove useful.
