Naim has long embraced two upgrade paths: the usual substitution route-replace an inferior component with a newer or better one and progressive power-unit augmentation for components already installed. Setting aside for now the former route: Among many other changes, these Naim "New Classic"-series components may be more easily combined not only with other components from Naim but with items from other audio makers. This enhanced compatibility includes Naim legacy systems: All can now be mixed and matched more easily.
Naim Audio's enduring, compact 200-series stereo power amplifier has been relaunched as the NAP 250, a key component of their new 200 Series. It has been updated massively in its technology and the compatibility of its connections, yet the primary circuit concept, which dates to the mid-1970s, is essentially unchanged. Recent development work has focused on helping the amplifier match up well with the new NSC 222 streamer-preamp, the NAP 250's intended companion.
The new 200-series power amplifier is now called, simply, NAP 250, dropping the "DR" of the previous model. But while the suffix is now omitted, the ultralow-noise DR technology has been retained in the active, fully regulated power supplies; indeed, it has been improved.
For comparison, I had to hand a very recent sample of the now superseded NAP 250 DR.
If it's not broke, fix it anyway
Over the years, I have tested several iterations of the 250. The outgoing "DR" version of the NAP 250 performed well in my recent evaluation in HiFiCritic (Vol.16 No.1). However, to better match the design and connectivity concepts envisaged for the new 200-series system, numerous operational and system changes were applied. That engineering process was allowed to run and run, resulting in a major design overhaul, sufficient to merit a fresh appraisal.

Listening to music inspires us to take action. Upon hearing an I.E.-Instant Earworm-we must then determine the best way we can go about listening to it again (and again) at our convenience.

In my review of the T+A R 2500 R receiver (August 2024 issue), I covered many of its features and took as deep a dive as time and column inches allowed.
Audia Flight FLS10
The dogma of separates has long reigned supreme among audiophiles: If you're serious about sound quality, you're supposed to need a dedicated preamp and power amp.
Totem Acoustic Element Fire V2
Totem Acoustic was founded in 1987, in Montreal, Canada, by a former high school math teacher named Vince Bruzzese. The company's first product, the Model 1 loudspeaker,' impressed me so much I bought a pair.

The Spin Doctor checks out the Kuzma Safir 9, a superarm from Slovenia.
The British audio scene from the late 1970s through the mid-1980s was pretty strange. Audio as a hobby was a big deal, with widespread appeal to a much younger crowd than today. Audiophiles were guided by a flurry of what my friends called \"hi-fi pornos,\" audio magazines that filled the racks at the newsagents.
Alex goes to Japan
Arriving in Japan from the United States is like being turned upside down. This condition lasts for much of the first week. When I visited in November, the time difference between Tokyo and New York was 14 hours. \"The floating world\" is a term for the pleasure-addled urban culture of Edo-period Japan, but it's also an apt description for the twilit and not-entirely-unpleasant weirdness of first arriving in Tokyo. Everything seems slightly unreal.
