Focal/JM Labs Nova Utopia Be

I'm going to be acquiring these speakers next week as replacement to my Dynaudio Countour S3.4s (a significant upgrade to say the least). Provided the size of the speaker and the low frequency response, I am wondering if any owners or previous owners of similar speakers have experienced any difficulties incorporating beasts such as these into a moderately sized room. My system resides in a 20' x 13' room with the speakers/electronics along the short wall. The corners, first reflection points and rear walls are acoustically treated. Additionaly, the stated nominal impedence is 8 ohms with the minimal impedence dipping to 3.6 . Would it be advisable to utilize to 4 ohm taps of my Mac amp rather than the 8s? Thanks in advance. New speakers is always both an exiciting and daunting venture...

Yes if you are using a tube amp then I found that that 4 Ohms worked best . I own Focals which claim 8 Ohms nominal but admit lowest impedances of 3.8 Ohm believe. My complete guess is that your average impedance is closer to 6 Ohms. I simply tried both taps on my amps. I suggest you do the same, but I think you will like the 4 Ohms output. It sounded fuller and more dynamic to me.

if you are looking at these novas be, you should consider the new stellaems... an absolute marvel in speaker technology... a direct decendent of the large g.u, this "petite grand utopia", has all of the attributes of the g.u in a smaller( but still formidbable size) foot print.
but , still ,the novas were /are very good as well. the stellas just take off from where the novas ' perfromance ended.

Thanks Focalfan and Mechans. I'm certain that the Stella's are superior to the Nova's in every conceivable manner. However, provided the current retail cost of the Stella's ($95,000 here in Canada), the Nova's at 1/4 the price are certainly the more economically effective solution.

You should always try the taps one up and one down from the speaker's impedance by ear, unless the amp manufacturer specifically warns against it. Very often the sound is markedly better on one tap than the other, and you want to know about that firsthand.
