The Curious Case of the Technics Integrated Digital Amplifier


Found this little tidbit, on Technics releasing a new digital (and I use the term correctly, but arguably) 70W/channel integrated amplifier.

Probably the best source of information is here.

Lots of curious things here.

  • Why so little power in such a large (for Class D) device?
  • There's no mention of the GaN FET's as in the Technics SE-R1.
  • They DO keep the phase/amplitude matching circuit of the SE-R1, but if the review is to be believed, does not make up for the other shortcomings.

Yes, this is a Class D amplifier, but Technics calls it a Digital amplifier, and based on how the signal is manipulated in the digital domain, so do I. There's a separate thread for this discussion, it's by invitation only, so lets focus people! :)

The reviewer describes the sound much like I have found old Onkyo and Emotiva to sound. Perfect and gutless, so I have to wonder if this is a specific DAC or ADC conversion that's going awry here?

Best,

The only issue I have with the SU-G700 is that all of the analogue signals are processed through it's A/D or D/A converter. Not preferable for vinyl fans. Makes me wonder what happens when the matching SL-G700 SACD/Streamer is hooked up to the amps RCA inputs. Is the analogue signal then going through the D/A converters in both the player and the amp? Seems odd. I guess there other all-in-one units that do this too. The Naim Uniti range being an example.
