Avi V2
I would describe it as very powerful and neutral. I use it to drive Shahinian Obelisks and they're not a particularly easy load. It drives them with consummate ease and in my opinion represents good value for money. It will reveal what's recorded without embellishment. Buy with confidence.
PS. I use the V2 Pre-Power with a Rega P9, RB1000 arm, Dynavector 10x5, Trichord Diablo phono stage and NCPSU through the Obelisks.
