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,

So it seems this is a rather narrow piece of kit, I assumed it was full-width, and as far as I can tell, they are using a linear power supply.  Curiouser and curiouser.
That review is dated February 2, 2015
Well,  I guess I'm behind the times, the review is from 2015, when was the SE-R1 released?
The one you refer to is the European version (SU-C700) and not the one sold stateside. The one sold here is the SU-G700. It looks slightly different and it looks like there is a lot in common but I can’t say for sure.I was interested in the one sold here but only found one review of it.

Here is a review from Andrew Robinson of Home Theater Review.

He really likes it and I believe he kept it. There’s also a YouTube video done by him:https://www.youtube.com/watch?v=9j1ekgzBiL8

All the best,
