Forgot to add one thing. The Lingo upgrade replaced a Valhalla power supply. I had the Valhalla upgrade done in 1982. The Lingo was a HUGE improvelement over the Valhalla.
Should I replace my LP12?
I've had an LP12 for the past 23 years. In that time, I've done all the suspension upgrades. It still has the Valhala supply. It also has the original Ittok arm, but a Goldmund platter. It has served me well and still works fine. However, I'm thinking that it might be time to go for a new, quite different approach to analog. I could save my pennies and get the Keel upgrade, new arm, etc, but maybe I'm simply ready for a change. I'm thinking I could get around $2.5k for what I have, including Clearaudio cartridge. My problem is where to go next for about the same money? The Pro-Ject tables look interesting as to the VPIs. I'd like to trade the LP12 signature lower mids for something crisper with a very sweet top end. I'm a tube guy so that might be considered a guiding principle. Any thoughts?
