To Hans Wetzel,
I read your review about the KEF Q750 speakers! My question is, do you know if another amp [other] than my NAD C 375BEE will deliver more enjoyable hours of listening? If so, which one? I read a lot about the Yamaha A-S2100.
That’s a difficult question to answer, Hans. There are an awful lot of amps out there, and many of them are quite good. Given that the Q750 is a pretty easy speaker to drive, optimizing sound quality would really come down to what your personal preferences are.
NAD makes great, no-nonsense amplifiers, and your C 375BEE generates 150Wpc into 8- or 4-ohm loads, which is more than enough power for the KEFs. The NAD is getting on in age, but truth be told, class-AB amps haven’t changed a whole lot in the past decade. If I were in your shoes and I was looking to invest in my system, I’d hold onto your NAD. Depending on how you listen to music, I might consider a new DAC or CD player, as digital front ends have not only improved dramatically in recent years, they’ve also become far more affordable. I can’t speak to the Yamaha integrated amp that you mention, unfortunately. If you wanted to swing for the fences and splurge, however, I would suggest NAD’s own M32 DirectDigital integrated amplifier-DAC, which I reviewed back in 2017. It’ll give you a cutting-edge digital source and latest-generation class-D amplification all in one box. It’s expensive, for sure, but it offers reference-level transparency and 180Wpc into 8 or 4 ohms. That should be all the amp you’ll ever need for your KEF Q750s and well beyond. . . . Hans Wetzel
