Magnepan 1.6QR : to bi-wire or not to bi-wire


Hello, everyone!

I'm looking into speaker cables for my Maggie 1.6QR and would like to know whether bi-wiring would improve the performance of the 1.6QR.

I understand that certain speakers do sound much better bi-wired while others would do not produce significant improvements to justify the cost of a bi-wire.

I've even heard that bi-wiring would cause the speakers to lose coherence between the bass and the trebles. Is there any truth in this?

Your experienced advise is most appreciated. Thanks!

Best regards.

I'm a long-time owner of Maggie 1.6QR's. I've tried a number of different speaker cables, and combinations with mine. I tried bi-wiring with Analysis plus Oval 9 cables (with pins) and really couldn't hear any improvement. This was with a pair of Classe CA200 amps run in monoblock (about 600 wpc). The sound was different, but not better. If anything, I thought the soundstage became somewhat indistinct. I had better results with simple mag-wire cables.

Anyway, if you can get your amps really close to the speakers, the length and type of wire can't make that big a difference. One of my biggest improvements was going to long interconnects and short speaker wires. YMMV

The biggest breakthroughs in sound for mine involved hacking the speaker:

* First, replacing the stainless speaker connectors with Cardas connectors, made a notable improvement, especially improving the quality of the internal wiring (I rolled up the socks to keep from cutting them--really easy!).
* then, about 3 months later, replacing the internal crossover with an external crossover, using high quality components (North Creek/Jensen)
* then, about a year later, going to a bi-amped system, with an active line-level crossover between the preamp and the amplifiers. The two stereo amps were hooked up directly to the drivers--one channel per driver--bypassing the fuse and connectors. This was HUGE!! A major step forward in clarity, detail, and impact.
* most recently, switching to tube amplifiers instead of solid state. I found that I could run lower power amps, and get much better sound. I have EL34-based amps on the tweeter/mid panel, and gain-matched KT88-based amps on the bass panels. No need for a subwoofer with this setup!

At this stage, the sound has progressed far beyond any other 1.6's I've heard. It's a bit more expensive than just buying another set of speaker cables though!

A lot of support to be had on the Audio Asylum Planar board. You should check it out!

Hope this helps!
