keep your SP9 and get an audio research amp like a VT50 and a Vandersteen 2wq subwoofer. You won't need much power when you use the sub and it makes my 2ce's sing! I have a set up like this and I love it!
Amp/Pre-amp for Vandersteens
I am looking to move up from my present system. Want to stay with VAndersteen 2cis. Front end is mostly CAL 10 changer with ocassional vinyl, so I need a phono stage. Total budget approx. $2500. Any thoughts appreciated. I am seriously considering McCormack DNA 0.5 or 1 DLX. Probably want to go SS or hybrid. Presently running ARC SP9 MKII and NYAL Moscode 300.
