Over the top

I've always wanted a pair of Guarneris and finally got a pair of new Mementos. I also had the C2200 and MC2000 years ago so with a little conjecture I can say I'm sure you're going to love your new pairing. What size room do you have the G's in?

The size of my listening room is approx 20 x 15 w/ high cedar ceiling that goes from 10 feet at the front and rises on an angle to about 14 ft

Nice choice of gear. You'll be in heaven. Just a word of caution - be careful not to overdrive those awesome speakers. The port is tuned at around 55 HZ - so be careful with any seriously bass heavy stuff (although the woofer excursion may be well controlled at 60 Hz - you may find that 30 Hz could cause excessive excursion given your massive power amps)

I second the REL sub suggestion...I have had the G's twice(?!) and the sub is a must if you want them as a main system speakers.

The thing with using the Guarneri with a sub in my particular setup does not work because my room gets overloaded with bass quickly. The construction of my listening room and the floor in particular are heavy on the wood. The floor in particular appears to be very flexible and "Bouncy" so that the whole room basically turns into one big woofer. I would advise anyone who is thinking of a sub to audition the sub in question in the room where it will be installed. Otherwise you could find yourself adding something negative to your listening experience. I listen to alot of opera and classical as well as jazz with mostly standup bass instruments. As one reviewer put it, the bass that the Guarneri does reproduce is VERY convincing so as not to miss deep extended bass. As I said earlier, when I listened to the Sonus Faber Amati there was no question they were full range and had deeper bass. However they did not sound as alive and did sound a little nasal and closed in compared to the Guarneri in my set up. I feel that if I did not miss deep bass on my Guarneri before with one Mcintosh MC2102, I think that with the change to the MC2301 monoblocs bass and dunamics should be even better. Not to mention the change from the C2200 to the C1000.
