It is always dangerous to nip into the shop. The guys know a lot about stuff, and you can feel intimidated or encouraged, depending on who you talk to. But you get ideas you may not have had, and not everyone is trying to upsell everything. Not least because if you are not happy, you can refund or exchange stuff. My latest visit opened my eyes to DAC's and cheapo amplifiers. I was trying to get a surround sound system working, and it all sounded pretty bad. especially music. Nice chap suggested a DAC for music, especially for headphone fans like myself. Genius. because no AV receiver is going to give you a hifi musical experience. (under a grand, anyhow). Bottom line is, after quite a lot of trial and error, I got a perfect system, and spent way more cash than I should have...
