As you might have expected of me, PENG, I read the specs before ordering. I suspect the problem is one or more of the following:\n\n- The 975 doesn't have an output level problem; it has an input sensitivity problem, and has substantially less than unity gain.\n\n- The 975 has an unusually low input impedance, perhaps because of a design defect, and is somehow stressing the cheap output devices of certain components, like the cheap Sony BD player. (I doubt this is the reason, but I don't know.)\n\n- The 2V output spec is simply incorrect, or wasn't met in the first version of the product, which I have. (I suspect this is the real reason.)\n\n- The ATI AT602 gain is not 28db, it is only 24db, which is woefully low. If you look at the ATI web site, which was my reference, gain is listed at 28db. If you read the owners manual, I just noticed it is listed at 24db. 24db, if correct, is the lowest gain I've ever encountered for a power amplifier. (24db of gain in conjunction with less output from the 975 than advertised could be a double whammy.)\n\nSo, I'm thinking this is a genuine case of components that are just incompatible, especially when the electronics chain is pair with a set of JBL speakers that are probably 82db\/2.83v\/m, sensitivity-wise. And I'm also thinking that y'all ought to consider the silliness of being so dismissive of a situation that when discussed gets an immediate match from an audience with such a small population.\n\nI did expect you to read the specs, that's why I asked for explanation instead of doubting you. And you did not disappoint.:D\n\nTo add to your list of suspected causes, I noticed that the output impedance is stated as:\n\n"Output Impedance (Main-RCA) <1 KΩ"\n\nSo it could be 999 ohms and that is not low for sure, but probably just a minor factor, as most amps, presumably including the AT602, should have input impedance >10K. Still, when you add everything up, that Outlaw is probably only good for amps with >32 dB gains.\n\nIf it has decent input sensitivity and reasonably low output impedance, even 1V can drive the 24 dB gain AT602 to its rated output but it certainly can't do anything to the ATI's larger amps.\n\nfmw may be right about in the majority of cases, but I do think it's time manufacturers be more specific about their preamp outputs. As it is now, it seems to me most of them are vague, you just can't draw conclusions without seeing bench test data. Fortunately so far any of my AVR, preamps and prepros have no trouble driving any of my power amps. I hope that Outlaw is the only one that failed you.
