Another option to consider - there's an integrated amp
'Tube Audio Designs TAD-60 w/extras reduced a lot' posted on Agon for a very nice price. No phono of course plus limited inputs. To offset the limited input concerns on the integrated amp I would use a Calrad multi input to one output good quality selector box which is less than $40. I got mine from Cable and Connectors in Conn. and use it to switch between 2 turn tables feeding one phono stage. Not sure on the efficiency of your speakers but the TAD should drive most speakers out there. AND - it sounds nice, very well made, plus Paul G of Tube Audio Design is a great guy to deal with for customer support/issues. Finally the TAD will hold its value. You can resell it down the road for close to what you'd pay for it. B&K amps are nice for the money, a great value but I'm guessing you'd like the TAD better. I have no association with the seller. :)
