@chayro nailed it, IMO. Patience is your friend here. It's hard to do, but it pays big dividends. Right now I'm tuning my DIY tonearm, and desperately want to put a big expensive cartridge on it - just to see what it can do. But I'm holding back until I sort out all the quirks. So I understand your impatience.
But consider - until you live with something you don't really know what you like; that only comes after you realize that you've been listening for 5 hours and still want more. Not the piece of candy that dazzles you for 20 minutes in the showroom. Patience, I say, and only get serious on your next attempt.
