What is my weak link?


I just upgraded to a Luxman SQ-30 tube integrated. My turntable is a Thorens TD 146 (auto stop/lift). Stock tonearm with Denon 110 HOMC. Speakers are Dynaco a25XL (recapped). I realize that the Thorens was entry level (in 1983 when I purchased). I think system sounds great, but, I have only old integrated to compare (Rotel don't recall the model). If I were to upgrade, should I start with TT or speakers? Or, keep what I have and use $ to buy more records? I know you guys hate these lame questions. But, I had to ask.

As long as you're happy, stay with it. Make sure you have good supports for the turntable and speakers. Try solid core 12 gauge mains cable on the speakers and upgrade your interconnects if using basic stuff.
If it moves your soul, then dont change it. If I were pushed for an answer. I would change that DL-110 on the Thornes to one of the Grado wood body Prestige cartridges $350-$600 range...They sell both low and high output ones so you can match it to your phonostage,these are all moving Iron types. This IS the cartridge for the Thornes, so I would start there. Good Luck.
I haven't heard your luxman but i suspect it's pretty awesome. i believe it's phono stage has low output MC capabilities. You might mos def wanna experiment with a few LOMC carts. I also upgraded from rotel amp/pre to a tube based amp/pre. I have found the most dramatic improvements in my system were mostly at the front end. also i agree with noromance about cables (solid core) and good support/damping for your tt.
Re "weakest link": your system is actually pretty well-balanced, at a certain price point. There's a lot to be said for that. Leave it alone.
