I've had this about 5 months or so - great condition. This dac replaced my modded Paradisea and to my ears is much better - much more extension in highs/lows - much more detailed with better drive and never fatiguing. Current retail is $899 with volume control. Paul says he can add the volume control to mine for $65. Prefer Paypal - shipping $15 within CONUSA - If price is met I'll include some EXCELLENT sounding RCA Cleartops - these really work well with this dac!
