This is my first post as I have just joined the forum - although I have been tracking this thread for a long time as a guest.
I have owned a Sennheiser HD800 and Vioelectric V200 amp for about 3 years and I loved the sound quality of that combination - using a Sony XCD5400 CD player as my music source (using Monoprice's balanced interconnect cables between the CD player and Vioelectric V200 amp). I decided to also purchase the V281 amp based on the many positive comments made in this thread. I only have about 15 hours of playing time (using a balanced Sennheiser headphone cable that I had to buy in order to run the combination in balanced mode).
I have two major questions.
Question number 1: In balanced mode, I have noted that my volume control is usually between 9 - 10 o'clock (when it was previously between 11 - 1 o'clock when using my V200 amplifier) for most recordings when listening at roughly the same sound volume. I noted that there is very little difference in the range of volume control when I tried it out at the -6 and -12 pre-gain setting and it is still no higher than 10:30 o'clock at the -12 pre-gain setting. By contrast, when I plugged my single-ended AKG K701 headphones into the 1/4" single-ended headphone outlet I could see a large difference in volume settings eg. ~10 'clock when set at 0 pre-gain, ~12 o'clock when set at -6 pre-gain and ~2 o'clock when set at -12 pre-gain. Why are these "expected" volume setting changes not seen when I run the amp in balanced mode?
Question number 2:
I only listen to classical music and opera, When I listen to a string quartet using the V281 amp in balanced mode, the dynamic range sounds normal - when compared to my V200 amp. However, when I listen to symphonic music recorded with a large dynamic range, I am having a problem. When I set the softer sounds (eg, when a solo instrument is playing) at a comfortable "hearable" level (that is compatible with my extensive experience with "live" orchestral music) then the music gets too unaturally loud (and raucous) when the orchestra plays full tilt (at fortissimo levels). I have never had this problem with the V200, which can play very loud, while still sounding perfectly controlled and not "unaturally loud". Could this be due to the fact that my V281 amp (and new balanced cable) are not yet "burned-in", or is it due to the over-abundant power that this V281 amp can potentially produce?
