Any chance you're in the New York area?? Hard to find a good audio repair shop here- I'm not kidding. Especially a place thats knowledgeable on the older Infinity models.

Have you done any work on the infinity Qb's? (3 way system: Emit, 4" mid & 10" butyl woofer). I have a pair of Qb's and they really sound great- better than a pair of RSb's I had for a short while- which is odd, as the RSb was the "improved" follow-up to the Qb w/ poly-p woofers. But sometimes Ive noticed when listening to music- the sound from the midrange becomes muffled in one speaker. It clears up and then becomes muffled again. Is this a problem with the mid driver or a faulty capacitor in the crossover circuit board or- as most people have said-the adjust pots in the back need cleaning. ?? Any advice you have to offer would be appreciated.

If you read my other post here, I have the Renaissance 90's. But the Qb's still look/sound excellent- so I couldnt part with them- When I have more room I shall set them up in a 2nd hi-fi system along with my collection of vintage Sansui & Pioneer receivers and amps. The Qb's are 4 ohms but the Sansui's & Pioneers are alright with them. The bigger Quantums might be more challenging- but my brother drove a pair of Quantum 3's with a Sansui AU-717 integrated amp (85W), no problems.

I'm driving the Ren 90's with a newly bought Odyssey Stratos. Its a very pleasing combination. I'm just concerned about the Parts situation for the future. Right now, the EMIM's used in the Ren 90's are down to the last few in stock and they sell for $330 each- Ouch!! I dont know if Infinity (HK) is planning to make just the membrane (diaphragm) available- which would be alot less $$- and usually its just that 'part of the part' that fails- based on my understanding- I believe it either develops an open or it gets scorched from excessive current.
