If you can't switch the speaker cables at the speaker (..a bit confused here in that you will apparently/possibly be hooking up your Quad 12L's) switch them at the amp connection, right?
I know, I'm probably completely missing something obvious - and sure it will be pointed out shortly.

Option 3 , have a set of balanced interconnects made that reverse pins 2 and 3 most likely the least expensive way to go

With regard to the phase inverter, I would not fool with it unless you know, for sure that you can hear the difference. The reason I say this is that it took me years to actually hear the difference it makes, and then, only with some very high resolution equipment. Everyone says you will hear a difference in the bass. To my ear it sounded like a small timing issue. I think it is a small tweak, at best, and if it was my system I would focus on many other things first. I believe Truman's post above is correct. You should be able to just reverse polarity on both speaker cables. Also keep in mind that CD's come both ways. About 50% of discs are made phase correct and the other 50% inverted. If you didn't know this, you have already been doing a-b comparisons without even knowing it. That's why I say it is a small difference at best. As for the preamp; that is very important to get right. A lot of people over look it when, in fact, it usually makes or breaks the system. My personal preference is that if I can't afford a good preamp, I don't use one. I much prefer a passive unit or a cd player that has a digital volume control. There is a rough standard that a lot of people go by when dealing with preamps. $3000 retail cost is where active preamps start to outperform passive units. Normally, I don't like putting prices out there as a minimum guide but I have found it to be true in this case. Hope I was able to help.

I believe the Wyred 4 Sound preamps, DAC's, and Integrated amps all have the polarity/phase invert feature on the remote controls. I have the integrated STI-500 and also had the DAC-2 which had that feature.
Additionally, the Cambridge Audio DacMagic D/A converter has phase invert, as does the PS Audio GCPH phono preamp.

The Atma-Sphere MP-1 and MP-3 are both fully differential and balanced, and both have a phase inversion switch. They also have the ability to drive very long interconnects even though they are all-tube.

Sorry my fault didn't realize I forgot to mention I was going to purchase the Quad 12L active. That's why I needed the phase inverter because the single coming from the SB2 in inverted due to the mods.
