Primaluna Dialogue Premium Integrated driving Magnepan .7 with Bypassed Fuses


Hi everyone,
I am a relatively new audiophile, joined Audiogon 2.5 years ago, and this is my first post. I enjoy reading the forum very much, and would like to say thank you to everyone who has shared their knowledge, wisdom and humor with me. For this my first post I am looking for advice: I have a pair of Magnepan .7 speakers with bypassed tweeter fuses, and I am wondering if I can safely drive them with my Primaluna Dialogue Premium amplifier. The amplifier has 4 ohm speaker connections, and using KT120 tubes in ultralinear mode it produces 43 watts per channel (per specs). What I don't know is how much current it can provide the Maggies which I understand draw a lot of current (I have not seen an impedance curve for the speakers). My listening room (aka living room) is approximately 13' x 16' x 7',  with partially treated walls and corners. The speakers are on the short side about 3.5' from the back wall, I sit about 7.5' away from the speakers, and I listen to music at around 60-65 dB (C-weighted), sometimes peaks in the low 70’s. So my question is: am I taking an unnecessary risk driving the Maggies with the Primaluna? Can I damage the speakers if I play them too loud? In case you are wondering, after I bypassed the tweeter fuse and attenuator connections, the speakers sounder much clearer and precise to my ears in my room with my system.

Personally, I would play the system for a few months with the fuses in place so see if there are any issues.  If you don't blow any fuses during this time, you should feel a little more confident bypassing them.

Your suggestion is logical. I am usually cautious with these things, and after a week I decided to take the risk and bypass the fuses. Hopefully I will not regret my decision, and I can still re-wire them back to the original configuration.

Some of the comments here think you're asking about bypassing fuses.  I understand that you've already made that decision and I'm sure you're experiencing better sound.  Fuses have no business in the signal path.  

I believe you question is just:  is 40 wpc enough to drive the Magnapan 7.1 at low levels.  My experience with large electrostatic speakers indicates the answer is  yes.
