Hey Martin,
Have you upgraded your TLP to Nirvana status yet?
I totally recommend it.
There is an appreciable difference.
Right now, I've got all the parts to bring it beyond Nirvana, but I don't know if I should install them now.
The TLP Nirvana has been in storage for a year, and my new AKSA 100 Nirvanas need their 20 hour break in (Hour 1 slated to begin sometime tonight

). Besides, BlackGate capacitors are supposed to take forever to come up to speed, especially with regards to bass (from what I heard).
Cheers,
