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.

https://www.whathifi.com/technics/su-c700/review

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,

Technics offers three tiers of ' performance ' Premium, Grand, and Reference and all three Classes appear to offer variations on the Basis of Hybrid High-Speed Linear Power Supply, JENO Engine, and GaN-FET Power Chips.

If you check the spec for SU-G30 Integrated it specifies GaN-FETs.

The Power Output for each Class is on the low side for an Amp with the SE-R1 at 150 WPC @ 8 Ohm being the most.
As for sound; Silent, Refined, and Resolving.
From Technics:  Delivering a sound with a rich spatial expression.
Not gutless definitely not.
Maybe not so curious after all.
Contemporary perhaps.

The release date is likely 10-12 months later than the press release (2017).

@mezzanine , whatever processing the grand class gear does the effect
is not at all bad.
Worth a demo ... two years ago only one favorable review for Grand Class gear was out.
My gear >>> TT >>> SU-G30 / Phono Pre playback is like I say not bad.
