Using a sub-panel to shorten the lengths of the runs is a good idea. Be sure to use adequately sized feeders to the sub-panel. It is also true that for 10 Ga, a 35 foot run is not a big deal. However, if you use a well placed sub-panel, you will minimize costs for cabling.
Theo is right about the 30A breaker. This is, IMO, a very bad idea. Theo's suggestion about 14/4 is interesting and worthy of consideration. You might also do a review on his website the ideas that Russ Andrews recommends.
Chriskeating brings up the point of verifying your ground system. This cannot be overstated. This should be done first. See the thread http://forum.audiogon.com/cgi-bin/fr.pl?fcabl&1102789057
for a thorough discussion of grounding systems and AC issues. Seperating the ground source for the runs to the audio equipment (seperate from the house system) is a no-no according to many local codes. Yours may vary. Some seem to have done it with success. If you add ground rods and bond them together you still get much of the benefit.
Using 10/3 in the manner you described with individual hots and a shared neutral and a shared ground is also a bad idea. Sharing the ground....maybe. I would not do it, but then I may be particular. Sharing the neutral is a very bad idea as you are then placing twice the return current flow on ONE conductor AND sharing all of the noise.
The thread above talks about a lot of this in great detail.
