Might be a bit late
I just reciently repaired my Purties. There is a good chance that the connector to the power supply board has come loose. The LED is connected by a small connector to the side of the board (left if olooking from the front).
I'm not sure how true this is. The Source has an 8" woofer not dual 6.5" aluminum woofers like Purity and they look like they have different panels. Source has black spars and Purity is clear. I noticed a better sound with the Purity over the Source..I'm not sure how much of that was amp related...
Wow, I love what you guys ended up doing with your website. Had it not been completed so well I would have hooked you guys up with a killer deal on a new one.
I'm gonna try and make it out to your next show. Maybe talk a bit about your setup as well as I'm looking into a pair of demo Summits.
I asked Jim Power this exact question and here is the diagram that he sent me. It appears that since the speaker level connections go through a pre amp that they do no pass through the amp.
I have a VSX-92 with the Purities using the pre-amp outs and am very impressed with the way they sound. For the price there isn't much out there that can compete. The built in amps (ICE) are also quite good and are used in many top of the range products including the new Elites.
Does anyone...
