A fabulous DAC in excellent condition. It is functionally perfect and 9/10 rating is only due to age. Nuvistor tubes (lined up like 4 silver soldiers inside) are rated at 100,000+ hour life spam and this unit has perhaps 2000 hrs on it and sings beautifully. The feet are really neat - they are lit and turn from orange to blue when the unit is fully warmed up. Was almost $3000 New. If using PayPal, please add 3%
