Aesthetix Calypso VS ARC Reference 3

Not sure how you measure the last 5-10%, or how you calulate twice as good? But to me, gear that has the ability to get it right (last 5-10% ?) is always at least twice as good as gear that can almost get there. I also think that extra performance is well worth the money at any cost.
Sadly, this does mean I can afford to get it.

I have had the pleasure of owning both pre amps.At its price point the Calypso is very competent,I never experienced noise issues.The REF 3 just has that emotional immediacy and correct sense of timing that was lacking in the Calypso.

In my system the Calypso just lacked dynamics and soundstaging and was a little grainy compared to the PS Audio PCA-2. I would like to try the ARC myself but was impressed with the Pass Labs X0. Although it could be a little bright on some recordings, it was very dynamic and transparent with a great soundstage. The low level detail was outstanding. But the remote and user interface is rather poor.

Have you considered the Modwright LS 36.5? It is the price of the Calyypso and the performance of the REF3.

The Calypso Signature should be out soon and the Hovland HP200 should be given a try along with the Wyetech offerings.
