Just a note to mention that my error containing posting which preceded the "Correction" above is missing in action. The correction, by itself, is accurately identifying two very different, and listenable, classic (soon to be vintage?) DAC's.
My vote for integrated amp is the Aronov LS960i, with its natural, and musical presentation. Some special attributes are transient speed, dynamics, and ability to enable the finest bass reproduction from any speaker I have paired it with.
To fully realize the quality in your integrated amp, also look into the interconnects, and speaker cables from greggstraley@yahoo.com
For unveiling the three dimensionality or physical presence of the players, and the performance space, together with the kind of fine detailing that makes you believe a musician or singer is right there in front of you, these wires are ridiculously low priced. $120 for interconnects, and $180 for eight foot pair of speaker cables.
They enhanced, or optimized three different systems where I tried them, so not system dependent. There is a version for system where there is any tube equipment in the signal path, as well as a version when only transistor equipment used.
