Hello Guys. I own a Sony PS-HX500 turntable with 2 upgrades: an improved belt and more importantly, a much improved cartridge - the Goldring E3 - this made a huge improvement in sound compared to the standard budget AT preinstalled one. The turntable has a build in phono that can be defeated - and I use it connected to the phono stage of my stereo receiver, the Yamaha RN-803D, as it sounds much better. So a question arises - would I benefit noticeably by buying an external phono premap? Yes, I know that getting a very expensive one, maybe even more expensive than the turntable (650 USD with the upgrades) would logically make a difference, but I'm wondering if getting a phono preamp of up to 300, MAYBE maximum 400 USD would make much of a difference, since I don't want to buy a phono preamp as, or more expensive than my turntable. And also, how exactly would it help the sound? I get it that it would preamplify the signal more, basically giving me more volume, but since I'm using my receiver with 2 6ohm bookshelf speakers and a 300w active subwoofer, and my receiver can push 130W into 6ohm (WAAY more than enough, especially considering my bookshelves are low cut at 80hz), I don't really need more volume. Thanks!
