Not very much to say about this combo : I sold my SP-15 some time ago which left me with these, sitting around and catching dust. Highest sound quality possible, the preamp works on batteries, therefore no interference with power network induced distortions. The units are as new and the needle was barely used. Everything worked perfectly back then (some 4 or 5 years ago), so I didn't test them prior to selling them, but what could have gone wrong... Anyway, if you want to be sure, feel free to come with your turntable and test them, I have no problem with that. IMPORTANT : Please take a look at my other auctions, I'm offering combined shipping, but beware : shown costs are valid for weights up to 10kg, shipped within the EU. My items can also be picked up in Brussels, at zero costs. Should this be a better option, contact me after the end of the auction, in case you win it. Thanks & happy hunting. :)
