Although the C46 has been out for awhile (5 years or so), this 2 year old C46 is still one of the best buys in a high end pre amp. I sold an ARC REF 3 a few months ago on AGON and didnt miss it with the c46 in my system. Time to move on, so this very clean C46, used in a pet free, and smoke free environment is now available. Priced to move quickly. If any questions feel free to call 619 851 6097 or email firstname.lastname@example.org. THANKS FOR LOOKING.
