Bryston 4B3 Like New 2Channel Stereo Amp Exc Cond! Free US Ship 6 Mo. [Expired]


no longer for sale

Bought from Audioadvisor less than six months ago and wish I could keep this amazing amplifier.  REALLY don't want to give this excellent, powerful, clean amplifier away and will still stand by my free US shipping... Have too many pieces of like-new equipment that must go and pay for new addition to family... Has more than 19 years left on their wonderful warranty! Silver, no handles, 17" excellent amp with no blemishes,scratches and sounds so clear and inviting.  I have two other amplifiers I may sell as well, but we are one car down and need to save up for a new automobile.  Please ask any questions and this amp needs nothing, only a good home to go to!  This is really a 10/10 but only has a handful of light use, hours on it here at my pet/smoke free home.  Thanks for looking and will upload actual pictures if asked.  Please add 2.9% if paying by Pay Pal. Offering FREE US Shipping and please contact me if you are in Canada.  Will work with you for exact shipping if in Canada, which the buyer will pay, UPS, Fed Ex, etc._________________________________________________________________________
