The problem with Tin Pan Alley is that it sounds good on most anything of quality. But, it is a nice demo tune and certainly can show the differences in equipment.
In this case, what this demonstrates is the difference in "snap" between the Yamaha RX-Z9 RECEIVIER in "Pure Direct" mode, and the Melton P/P KT-88 tube integrated amp rated at 80wpc (no feedback). Source is an SACD on an Oppo BDP-95.
The difference is really obvious. These were recorded on a Nikon D750 DSLR and the tracks are within 0.2 dB using pink noise.
