I'm not trying to get you to throw more money into something that you just may not be into, but...
Are your albums clean? There's no substitute for a good steam and vacuum cleaning to my ears. Vacuum cleaners don't have to be expensive (relatively speaking) - my KAB USA vacuum cleaner was about $170 and truly elevated my vinyl sound quality. Combined with my $25 or so hand held steamer, it's gone up another level.
Second thing - have you considered the Pro-Ject Speed Box? It doesn't just change speeds, it's a great sonic upgrade. There's no tradeoffs with it sonically; it's an across the board upgrade. It easily made my 1Xpression sound better than the next deck up the line. It's about $130 or so nowadays.
Thirdly - Acrylic platter. Combined with the Speed Box, it's like a different and far better deck. I think it's about $100.
But for about $250 or so between the acrylic platter and Speedbox, you may be better taking that money and selling the Debut and buying a better deck IMO.
But again, don't force yourself to try to like vinyl. You may convince yourself for a little while, but in the long run you'll come to your senses and kick yourself in the rear end if it's truly not for you. The best way to know is to hear some better decks. Hopefully you've got a dealer or two locally that has one or two set up on the floor. With dealers closing everyday and turntables being a niche within a niche, it's not easy to find one though.
