I recently purchased an EC Balancing Act in great condition and it has a $300 upgraded P&G 10k pot. I am running it with KR PX4s and an Osram B65 driver and love the sound.
My issue is that on a number of CDs, where they are recorded at a much lover level (yes, I am still using a CDP most of the time), - and think Reference Recordings classical CDs as an example here, I can turn the EC volume knob all they way up and it still is not anywhere near the volume I get from my EC ZDT or ZDSE. With my ZDSE in the same configuration, for example, I get much higher output levels on the same CD at 1:00 o'clock than I do with the BA running fill tilt.
Also, I have noticed that the increase in volume on the BA's P&G pot over the last 1/3 of it's range only increases the volume slightly (in other words, it seems the last 1/3 of the pot's range hardly increases the output much).
On many if not most of my stuff, the lack of output is not a factor as I am getting the volume I want (albeit at a much higher level on the pot than on my other EC amps) but this is an issue on at least 40-50 of my CDs that I do listen to frequently.
I'm not as technically experienced as many here and it puzzles me because I have always heard that the BA can drive any headphone and my Sennheiser HD-800s should not be a hard phone to drive vis-a-vis other phones.
Am I missing something here? Is this normal for a P&G pot? Is something wrong with my amp or a tube?
Thanks in advance for any help (PS, while emailing Craig back and forth a few weeks ago about another amp, I had approached this issue while asking a number of other questions on his 2A3 and 445 amps, but he may have missed it as his answer did not address it).
Thanks,
Frank
