M. Logan Requests- Tube Suggestions in $1.5-2K??

You may want to check out Classe Audio as I use two Classe 25 amps with the Class CP-60 preamp with my Ascents and the system sounds nice. I find the Classe amps work great with Logans, I also use a Sonic Frontiers SDF-2 tube D/A which matches well also.
