Problem 1) The Gamma 2 does not obey windows/OS level volume control. This is VERY annoying, as it means that I have to individually control every single application's volume individually. Its not that bad for music/video because thats just 2 apps. Its horrible for firefox, where each instance of flashplayer will create its own volume level. Its horrible for video games, where they default everythign to max volume and it takes quite a few clicks to get into sound properties.
Problem 2) I have no amp for the HPM-60 right now. On the back, they say they want 30 watts each, max of 60 watts each. They have a resistance of 8 ohms and a sensitivity of 92.5 db/W at 1 meter distance. They are about 5 feet (2 meters) away from my head. Does that mean I need a 2 watt per channel into 8 ohm amp to drive them to proper listening levels? 92db is a butt-ton. I dont know if I did that right. I'd love some enlightenment on this.
Problem 3) A5's, HPM's, and subwoofer each will have their own respective volume knob. Maybe the HPMs wont even have a volume knob depending on the amp. There is no OS level volume control. Software level volume control is very very finnicky. I have to set youtube about 3 pixels away from mute to make it a reasonable volume. Same with many other flash games/websites. Tons of flash games dont even have a volume control option built in.
Problem 4) A5's, if you turn them too low in volume (under 25%), will cut the active speaker out and only play out of the active speaker. Ideally, they should be played at 50% volume. They expect headphone-level voltage input, though. What i'm giving them right now is line level inputs. So I have them turned to the lowest possible volume without causing a channel imbalance, matched the subwoofer to their volume, and they are decent sounding so far. This is not at all ideal.
So here's the trickiest part: I need the OPPOSITE of a mixer. I THINK. A mixer takes a bunch of inputs, volume matches them, and sends it out of 1 output. I need to give the mixer a single input, send it to a bunch of outputs, and volume match the outputs.
What is this device called? Does it even exist outside of multi-thousand dollar studio equipment? I was looking at preamps but it seems that they are pretty expensive even by themselves. I was also looking at DIY solutions like distribution amplifiers and such, but didnt find too much.
So far the only solutions i've come up with is to 1) buy a new DAC and sell off this gamma2F++, or 2) find a preamp that has 3 seperate stereo channel outputs + headphone output (or 2) and then volume match the active/passive/sub at a proper volume, and THEN use the preamp to bring it into check. or 3) get a decent AV reciever that supports multiple sets of speakers and has a headphone jack, and use the headphone jack to power the A5's. A5's require either headphone output or pre-amp output.
As you guys can see, i'm in quite the tizzy. I'd greatly appreciate it if I could get some help.
