Selling one pair Musical Fidelity 550k Superchargers in original shipping cartons and with all accessories + manuals. Sounds FANTASTIC when paired with my Pathos Acoustics TT-RR (also for sale, see my other listings) and B&W Diamond 805's w/ Velodyne Sub. Unlimited dynamics, clean, sound carries true to what ever amp you partner with it with (Tube, SS, or Hybrid). Can be used with S.E. Line inputs as stand-alone Monoblocks or (as in my case) via speaker level inputs to boost the gain of a low output amp (the Pathos is only 30 WPC SE Class A). Best system I have ever had, and I have had quite a few. Replaced with NAD M2 in my house to keep the peace with Spouse and her decorating concerns (yeah, I know, but I like the woman I'm married to). Purchased new from Audio Advisor 4-5 years ago, original owner.
Email Me with Questions, happy to answer. These are PERFECT if you have a low-wattage warm sounding SE Tube or SS amp and are looking for some fantastic dynamics to boot. They deliver a really delicious, intoxicating sound when paired with the above. (My personal experience).
