Technics SU-R1000 - Good but not the king of switching amps


Was looking at the measurements for the Technics SU-R1000 Integrated published by Stereophile. I never bother with the reviews of the sound quality as there’s 1 reviewer there whose ears I trust and it’s not this reviewer.

To be clear, this IS a digital amplifier, and is not a Class D amplifier. Atmasphere will always disagree with me, but given Technics nomenclature and the use of an A/D converter, and PWM output I think if any amplifier qualifies as digital this one does.

What I find kind of interesting here is that the measurements are OK but not absolute Class D killing results. I am particularly unimpressed by the performance of the impedance compensation circuit, LAPC, which at the end of the day does not seem to have performed significantly better than actual, non GaNFET amplifiers, particularly in removing the effects of the output filters Class D amps require. I really hoped to see a huge win here... but it’s not. It’s just making the PWM perform almost as good as a true Class D amplifier.

I have not heard this integrated, but the claims and expectations laid out for the technology seem to not be proven in the measurements. This is a very expensive integrated that does everything differently, and measures about the same as previous generation, also excellent sounding, Class D engines I’ve seen measured.

My stance that Class D was already very good and that new, faster switching amps would have to be truly spectacularly better to unseat them remains, in my mind, uncontested.

Can’t wait to see everyone trashing Class D on the measurements suddenly decide that this amp should be heard and not measured.

I demoed this amp against a Luxman and Chose the Technics. I love the sound and have owned this unit for almost 1 year.

Just wanted to dust this off.  I've heard it and had it in my system.  It's a superb, full stop, whatever name is on the badge.  Ironically, I also know someone who ditched his Luxman amp and Backert Labs Preamp for this and he doesn't seem the least bit sad about the change.

Thank you for bringing your Swiffer 😄 
I have the "lessor" SU-G700M2 which the Absolute Sound called "a taste of the ultra high end for a tenth of the price." I wish I could afford the SU-R1000 but a "taste" I can live with. 

All the best,
