What cables do you have? It's possible a change in cabling may be a cheaper alternative. A warmer cable such as Cardas,Purist,Audience,Transparent,MIT would do the trick.
Amplifier for Avantgarde Duos
I'm looking for an amplifier for my Avantgarde Duos. I'm currently using an Art Audio Carissa with an ASL Flora for the pre. With this combination I still get a shrill presentation on some recordings. My pre has a nice rounded top end so I feel comfortable with it. Does anyone have any suggestions for the amp. Again I prefer something that softens the shrillness. Some amps have a lean top end. The Carissa is almost there.
