Linar Audio P2 preamp. Designed by Victor Sima, one of the best. Class A operation. Dual-mono design. Truly balanced layout. Five sets of single ended inputs, one set balanced input, three sets of single ended outputs and one set balanced output. Removeable 15 amp power cable. Original box and manual. Remote control. Microprocessor controlled volume system. You going to spend 3-4 times the retail amount of this preamp to get better. Sounds great. Looks great. Purchased from authorized local dealer. Warranty extends to all buyers of this unit. I would guess about 2 years left. I've had about a year and am getting away from 2 channel audio for a while. Shipping and paypal extra.
