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.
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.

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. Jerry |
@classic8 : Hello… I had MG-1.7s, and now MG-3.7s driven by a Music Reference RM-10 amplifier (35 wpc), and I listen to music in a slightly larger room than yours, at slightly higher levels with no problem at all. I’m enjoying some of the best sound ever with this combo after many years of using Magnepans with many different amplifiers. You should be just fine. Incidentally, I bypassed the fuses in my 1.7s for years without issue. I haven’t done so with the 3.7s. Happy listening! |
@classic8 : One caveat I’d like to mention… I use Speltz Zeros to double the impedance that the amp sees, and I’m using the 8 ohm output taps. I didn’t notice a big difference in sound, but it made me feel more comfortable with using a lower powered amp with low impedance speakers (electrically). |
