MHDT Laboratory Canary
MHDT Lab's Canary use 4 x Philips TDA 1545 chip and the GE5670 tube as a output buffer. The TDA 1545 is the last production model from Philips. The TDA 1545 was supposed to be the new TDA1541A. But the soundsignature was different and it created its own dedicated followers. In the market we see TDA 1543 which came out before. TDA 1545 is seldom - why we dont know but it is for sure better than the TDA 1543. The recipe is the same as the other 6 models. No oversampling and no filter. The components is of high quality. Because of their sound the various components is selected to be used in their specific position. Build quality is among the best. Again like all the other models this unit provide 4 digital inputs - BNC, RCA, Toslink and USB. Output is RCA. Check the web for the many fine reviews on this analog and organic sounding R2R dac.
