Thank you for these excellent suggestions. I now have the Avantgarde integrated model 3 amplifier which sound fantastic for these speakers. The shrillness has disappeared and now I have music. I'm still looking for the equivalent in an amp pre combo which more readily suits my setup configuration. Are there any thoughts on Pass amps? The other consideration is amp/pre impedence matching. How much does this affect the sonic outcome?
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.
