Try not to analyze your listening much. Chill during these hours of listening. Enjoy!
Quandary
I’m really happy with my system. However when a technician, who is also a salesman, came to my house for a stereo repair he complimented my set but said it would sound a lot better if I switched out my Benchmark AHB2 amp (which I think is great) for a Pass 30 wpc class AB amp. He offered to let me hear that amp in my system so that I could decide for myself (at a fee of $300.) The only problem is he doesn’t have the 30 watt amp in stock but would have to demo the Pass sound with 60 watt monoblocks. He assured me that with my very efficient GoldenEar Triton 1 speakers the 30 watt amp will almost have the the same quality.
Do you think I can honestly judge how the smaller amp will actually sound? Or should I cancel the demonstration (and save$300?)

Mr.D I’m aware of the phase inversion on the CJ and have the correct configuration of the leads. Thank you for your suggestions. I’m trying to just listen and enjoy. The problem I’m facing right now is, because the CJ has no remote control I have to get up and down to change the volume for each recording. What’s worse is that the tiniest turn of the volume dial creates a difference in volume. Very disconcerting.

@rvpiano , because of the additional gain of the Pass amps, the setting on your CJ volume control is lower and that incremental adjustments are harder to pinpoint. I am not sure what to make out of "I have to get up and down to change the volume for each recording". This should have been the case with the Benchmark (I too make regular volume adjustments from 1 recording to the next). However, what I believe you might be experiencing with the Pass, is a "greater sense of dynamic range" as they have extraordinarily large, beefy and well designed power supplies. Try and relax with the volume setting as this should not be disconcerting. |
The gain on the 30.8 is the same as the monos so it would likely be the same with the volume control setting on your preamp. You are likely using the volume control closer to the 12-2 o’clock position with the Benchmark. Most amplifiers have gain of 26db or even more (was at one time the industry norm), so this volume situation will still occur. Volume attenuators (the kind used in the PV11, with wipers) are actually better when they are used at around the 12 o’clock position or higher (the higher you go the less resistance within the wipers). Your PV11 has 20db of gain, which is greater than most, ime. You can always have CJ, or a good tech, lower the gain, or even replace the attenuator with something like a Khozmo unit, but this is jumping ahead. Not sure what else I can say, but if this is a problem and is disconcerting, you might have your answer earlier than after the full weekend. Pass is not at fault here, but the gain issue seems to be, as suggested by yogiboy above. My best, MrD. |
