Hey guys, I am the first to admit I'm a moron when it comes to turntable stuff and did a little research, but still need some help, so I figured I would ask those vastly more knowledgeable than myself on the matter.First off, my father just purchased a new Vizio 65" TV(not my choice), but my brother and I purchased a Yamaha YHT-397 5.1 surround system to hook up to his TV. Now, this doesn't have a phono hook up and neither does my brother's(still lives there) LG 6820 5.1 system. They really love their vinyl, but I don't think they know the ins and outs of it, as we tried hooking up my brother's turntable to his 5.1 and it wasn't very loud. My knee jerk reaction was that it was missing an amplifier and after doing a bit of research it seems I was right, so....
My question is out of the 5 billion turntables they hoard, do any of them have built in amps that they could use by themselves?
They have:
Toshiba SR-F770
Pioneer PL-950
Technics SL-3300
Technics SL-D2
Some "Ion" modern turntable
Sansui SR-535
The next question would be, do they just need a phono-pre amp if none of those work by themselves? I've looked a few phono pre-amps, but I have zero clue what separates a $17 one from a $20,000 one(Yea I really saw one running for that). What makes some phono pre amps better than others and which ones would be good candidates to hook up to the LG 6820 5.1 and Yamaha YHT-397 5.1 systems that they have? Ideally, something under $100 would be preferable, but like I said I don't know the ins and outs of what's worthwhile, which is why I'm here.
Any help would be much appreciated as we would like to set up their turntable to run through the new Yamaha YHT-397 5.1 that is being hooked up to the new TV.
