I can't thank you guys enough, this is great and more than I possibly expected.
1. I will be swapping out the MoFi for a Manley Chinook Labs Chinook special. A new cartridge is in the works as well.
2. I have been pricing out REL's and that trigger will be pulled near term.
3. The question above by curiousjim bring the conversation back to the original intent. I have had questions in the past whether to upgrade from the PL was the right way to go or not. This posting was triggered by reading an exchange in a Vienna Acoustics group re: what amps people were using with their VA Liszts. While there weren't a huge number of responses to the question, the answers were startling in that people were using some serious amps to power their systems (Jeff Rowland, AVM, Devialet, Gryphon, Soulnote, etc). I began to look into a number of integrated amps (Rowland, AVM, Hegel, esp. demos) but was not sure that that was the right path.
This exchange has been a real eye opener and I'm looking forward to seeing the impact of upgrading the phonostage, cartridge, and subwoofers. After all that, I'll reconsider the integrated amp, although I do not rule out separates. Thank you all very much again.
