Relying on other people's opinions, reviews and assigning way too much importance to specs - including impedance matching - without first listening. Sorry, but looking towards these things without critical listening and evaluation in your own listening environment will get you nowhere. I'm not saying you can squeeze blood out of a stone, but a "match" or "mismatch" might not be what the numbers really say; and should be irrelevant if your ears are telling you something else.
It took me months to put together my system - each component was listened to for weeks before I wrote out a check. Yes, I used a dealer and paid retail (huh?) but in exchange I got to audition gear in my own room, got help and advice on setup, which cables etc to try and had the luxury of rearranging, tweaking and evaluating until I was happy within my budget. If I solely relied on specs, then I would have never purchased my 2A3 SET back-up amp to plug into my 6-ohm 86 db speakers with networked cables in a 27 x 15 ft room. Sounds great for my purposes - even though the math says otherwise.
