Lovely sounding and inexpensive DAC from Beresford modified to super-fi standards with new Wolfson DAC, new op-amps and new capacitors.

The TC-7510 with the lid off Close-up of the DAC and replaced output op-amp. The original PCM1716 DAC chip was replaced with a high quality Wolsfon WM8716, and the bog standard LM4556 op-amp was upgraded to National Semiconductor's exquisite LM4562. The four electrolytics were replaced with Black Gate types. The sonic improvements spoke for themselves! Another shot of the insides Close-up of the replaced DAC chip. The pins on the chip package are 0.3mm apart, so lots of care is needed when hand-soldering. Not a job for the faint hearted....

  • Beresford TC-7510 upgraded to Jim Beresford's MOD21 specification, plus upgraded output op-amp and DAC chip
  • Op-amp upgraded from a bog standard 4558 type to National's excellentLM4562
  • DAC chip upgraded from the Burr-Brown PCM1716 to Wolfson's WM8716
  • Black gate electrolytics added in the output filter section.
  • What a difference! The sonic benefits speak for themselves with added clarity, much improved imaging and simply more detail. The customer asked us to upgrade his newly acquired TC-7520 in the same manner, and the improvement in sound was excellent too. A worthwhile upgrade to an already excellent DAC.
