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?)


Right now the Pass seems a little “overwhelming” and not quite as detailed as the Benchmark on some things. I have to keep the volume knob way down. However it certainly fills in a lot of gaps in volume that the Benchmark lacks.
I suppose that was to be expected.  

OK, the $300 is invested.

If you would decide to go ahead with purchasing the Pass amp maybe (if you haven't already) it's a good time to discuss in the unlikely event that you feel the single chassis Pass is not a significant enough improvement to warrant the expense, the method that this would be handled.



If you have to turn the volume way down then it is a gain mismatch with the preamp that you are using!

The Benchmark amp has three levels of gain via a switch on the rear panel. The highest gain of the Benchmark is 22db. The standard gain on the Pass is 26 db. Quite a difference when dealing with the same source/preamp; more than 3db of a difference. This should not be an issue with the CJ PV11. For the same in room volume level, you will be lowering the volume control on the preamp...no surprise here. The PV11 is phase inverting, meaning somewhere in the system you need to invert phase. Unless there is a phase reversal switch somewhere, this is usually accomplished with the speaker cables at either the amp end or the speaker end. At one end only, the positive wire gets connected to the negative connection of the amp/speaker, for each channel. Not meaning to confuse you rv, just some insight. My best, MrD.

Try not to analyze your listening much. Chill during these hours of listening. Enjoy!
