This just in from a customer. We upgraded his DAC4800A, originally purchased in 2008, and still going strong:
"The amp is wonderful. I bought my first equipment, mono, with Christmas money in 1956 from Sam Goody.
Now it sounds like I always hoped it would. Mac components, a 15" subwoofer, and the DAC - I let it roar, and bathe in the music!
Many thanks --"
