So I've been testing a bunch of things and trying to figure it out. Unfortunately, changing vinyl setups is a ton of work and most of the stuff I have is low-money, which can sound awesome, but it means I'm only hearing a small section of what's available. But, I've come to conclusions.1: All of the preamps I've tried (including an EC preamp) have noticeable noise floor when I turn up the volume to some normal but louder listening volumes (gonna guess somewhere between 70 and 90db). This is when I haven't plugged in the table yet. Maybe there's a better way to solve it.3: Preamps make a bigger difference to vinyl's sound than amps, though I'd say on par with DACs, having recently compared a bunch of amps recently4: Marv is right, it seems like there isn't a consistent upgrade path, there are like 4 going in different directions. In fact, I was thinking of how a tube preamp might sound and I thought to get the resolution I'd need, I'd probably want a great transformer, like the one in the Studio an then I realized I was $$$$ in the hole and I hadn't even bought a $$$$ tone arm, a $$$$ cart or a $$$$ table. It'd be nice if it was a bit more settled like everyone is with the HD800,HD650,HE-6,Stax-something and the UERM.5: You sure can get a lot of table for $$: My AT440MLA w/ Technics SL-1200 Mk II sounds pretty great out of the TCC-750. And with the power mod, I bet it'd sound even better. I wonder if I'd like a MC cart like the Denon 103R even more.Also, I'm super curious to try a MC cart as I've only tried MM carts. I'm hoping it will be less likely to pop and click which drives me crazy.
