Sonical differences btw. Concentra II and Concert

FP- Having owned BOTH pcs. I could NOT tell a lot of difference sonically between the 2 - both sound wonderful but not a lot of difference. The new unit will be a little cooler to the touch and will play a little louder (more power) but I personally did not experience (almost twice) the rated power of the C2 - I was using Thiel 2.4, SimAudio Eclipse (balanced) into both pieces - To play these speakers fairly loud I would have to use (60 out of 100 displayed) on the Concerto and 72 (again out of 100) on the Concentra 2 _this is not totally scientific -just a personal (reasonable) observation - Again both are fine pieces but there is not a lot of discernable difference MHO

FP -A Concerto is basically 2-201s with an attached preamp-I do think separates provide more current(my EAD has more bass than the concerto)to drive your speakers-this is an obeservation but I feel its honest - I would use a Synergy2i and either a model 10 or 12 or 300 series amp-I had a model 10 with the synergy and was a good, powerful match - To replace your Rowland(with separates) would involve upping your budget by at least 50%_ I feel it would be worth it sonically , however, thats quite a jump in price to get there...
