I'm selling my Parasound A21 power amp in lovely condition - bought recently here from Awkwardbydesign and it lived up to its reputation of providing excellent SQ with loads of power and a large Class A bias. So much so that I've decided to get a class A amp in the Sugden A21 so sadly the Parasound now needs a new home as I've been ordered says no more than 2 systems at any one time. It is very heavy but has original packaging and UPS will deliver it. I'm in north Birmingham and can meet up within reasonable distance or ship via UPS.
Photos to follow later this week. Price is £1400 + delivery charges.
