For your budget, consider this combo new today on Audiogon:
"Msb link dac iii DAC with P1000 with nelson update/option" -- very reasonably priced.
By the way, if you use "an inexpensive CD/DVD player," then to some extent you'll limit the sound of the DAC -- the quality of the CD transport or digital source does matter. A good DAC can make a positive difference but will reflect what you feed into it.
Your Martin Logan/McIntosh components deserve a good source. Maybe keep on the lookout for a used Cambridge Audio 540 or 640 Version 2 CD player, or a Rega Planet 2000? They go a bit beyond your 300 buck range, but are fine players -- unless you're avoiding CD players due to the prying fingers of two-year-olds.
