Audiophile Quality 2 Channel DVD Audio?

The next step on my higher end audio journey is to explore DVD audio. Mostly classical, historic, and acoustic concert performances. To see Monteaux conduct the Chicago Symphony, or a Bayreuth production of the Ring, Segovia or Eric Clapton play in an intimate setting would add a huge dimension to the aural experience. So my question is: Does audiophile quality 2 Channel Audio exist? Multi-channel formats seem to dominate, and "Oh yeah, DVDs play 2 channel too." Just how good is it? Rather than replace my very satisfactory modded Sony sacd player, I plan to add a used DVD player through A-gon. Much DVD programing that I'm interested in won't have high definition video, and enough has already been said about the consumer being held hostage in the HDCD and Blue Ray format war. So for my needs, Audio quality trumps Video quality. Life is compromise. What's affordable that has great sound, or can be modded? And what's your opinion on the future of DVD audio? Thank you in advance for your insight. A-goners are simply the best.
