Hi David,
I have been using the Aesthetix Calypso with Genelex Gold Lion tubes that I got from Kevin Deal of Upscale Audio. A great upgrade from the original stock tubes. The preamp has worked flawlessly from the time I purchased it. Its a neutral sounding pre , highly musical and bullet proof. Its a match made in heaven with my Jadis. I would highly recommend the Aesthetix Calypso ( with the tube upgrade, or you can also get NOS Telefunken, albeit , a little more expensive tubes & get an even better sound sound )
