Speakers for Simaudio

Tarantula...your speakers are rated at 87db for sensitivity and nominal impedance is 4 ohms. The Simaudio i-1 is rated as a 50wpc integrated into 8ohms and it doubles to 100wpc into 4ohms, so it could be that your speakers are just presenting too difficult a load to the i-1, although your room is small enough that this may not be too problematic (unless you like to really crank up your music). So it could be that you may want to go one step up with the amplification and borrow an i-3.3 (100wpc into 8ohms and 200wpc into 4ohms) from your dealer just to see what that combo sounds like. Also if boomy bass is your primary concern than you should definitely be able to address some of that with either speaker placement and/or room treatments. Here are two pieces that could help you experiment with speaker placement:

Hope this helps with experimenting with speaker placement.

How about Zu Essence with Moon i-1?

Tarantula...you can get the Zu Essence with a 60-day in-home trial and if you don't like them send them back. Zu has decided to bypass dealers and is selling direct and as part of that roll out is giving prospective buyers 60-day "return privileges": http://www.zuaudio.com/

Two things..IMO you should never try to match a speaker to upstream gear,always buy speakers you like and match amps etc with it..Secondly ,the speaker/room interaction is one of the most important factors and sometimes overlooked..Your system will only be as good as the room its in...
