Or, keep what I have and use $ to buy more records?
In my Opinion, That is always the answer if you are a music fan and you have a limited budget. You already said you think the system sounds great. Don't muck it up. Listen and enjoy.....
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.
