Should I get the Art Audio Jota


I'm seeking advise on what I would think should be an upgrade. Would the move from a cj Premier 11a to an Art Audio Jota (high current model) be recommendable within my system.

From what I know from some reviewers about SETs and I have read a lot the Mini Utopias will be successfully driven by the 24 watt Jota (high current version).
Some SETs have even been reviewed driving the Mezzo Utopia which is a heavier load.
24 watts of SET power is not the same as any other 24watts.
In the SET category a difference of 5 watts is a lot.
Some reviewers have driven the Wilson Watt/Puppy 7 (nonimal impedance 4 ohms) with a 23 watt SET to a satisfying results.
It is true that the Watt/Puppy is more sensitive than the Mini Utopia but still they are a heavier load having in mind their impedance variations.
The Mini Utopias are relatively small speakers having a nominal impedance at 8 ohms (Correct?) and I think that the Jota will drive them to satisfying levels.
At least for me ...
Your pre-amp should do in my view.
Phaelon, I have read from the review in 'Enjoy the music' that the CJ 17 LS inverts the phase. You need to take that into consideration and reverse the speaker terminal connections.
The Jota has an input sensitivity at 400 mV (0.4V). This would mean that probably you can run the Jota without a line stage by either:
- use a passive volume control stepped attenuator and selector like Goldpoint or other passive pre-amp or
- order the Jota with that same type attenuator (if your intention is to order it).
Then you may just not need the CJ.
