Introducing an old NAD owner

Hello. I'm a newcomer who has had basically the same system for 32 years. Yes, I am starting to think about upgrading more of it. I'd really welcome suggestions. But it's also possible I won't take them, because ... well, it's complicated.

Back in 1988 I bought a NAD 7020e and a pair of 8020e speakers. I considered it a starter rig that I would replace a few years down the track. The 8020es are front-ported 2-way bookshelves actually made by KEF. The 7020e is a sleeper, a 3020e with a no-drift tuner added; the late Martin Borish, long-time NAD MD, is said to have regarded it as the best thing the brand ever made. Count me as a believer: I replaced the NAD 7020e with a Cambridge Audio Azur 540R in my main listening room for a year, then listened carefully to the two of them side-by-side, and went back to the NAD.

I now feed the 7020e from a silent PC running MusicBee, and a Synology NAS full of FLACs and MP3s, via an Audioquest Dragonfly Black. I recently added a REL T2 subwoofer to the mix, connected via the Neutrik Speakon cable to the NAD's speaker terminals. It has made a real difference, dialled down low enough to almost disappear - until you turn it off. I also had the terrific Chromecast Audio plugged in for a while. It's impressive what you can feed an older amp.

My next obvious change is probably to move the speakers to the family room. I auditioned some replacements about 15 years ago, and didn't like any of them quite as much as the NADs I already owned. But now there are affordable KEFs (Q150s? 350s?) and secondhand Dynaudios (Emits? Excites?).

I should probably also find the 7020e's natural successor, maybe a secondhand Cambridge Audio CXA60 or a Marantz. But while the NAD may not have the world's best audio, it has proved remarkably adaptable and durable. I had the internals cleaned up last year by a specialist. And I'm so used to its sweet, warm sound that I suspect it's possible I won't like anything else.

I owned in the 80ties a NAD 7130 some years ago I did bought a used NAD C370 for under 200 euro's. The difference with the 7130 (more ore less comeparble with your 7020) is considerble especialy the thight lows you get an way more effortless sound. The only amp's with enough juice an price quality that i can find are the Hypex Class D amp's. If mine C370 will break down and/or can't be repaird i would chooce with no hesitation for one of the Hypex amp's. Still i'am quite qurious how a NAD C370 will measure against an Hypex amp.

I have had a mono class A amp's which cost compared with new price atleast 6 or 8 times the price of a NAD C370 can a sure you you don't hear 6 or 7000 euro difference by far. This amp is in 1999 and 2000 amp of the year it has an power reserve insane for the price. Quote; "Into 8 ohms with both channels driven, it still comfortably exceeded its specification, at 172W (22.4dBW) at the usual clipping point of 1% THD. https://www.stereophile.com/content/nad-c370-integrated-amplifier-specifications

NAD C 320bee here. Yeah, the C 370 & the power amp equivalent C 270 are probably a really good deal if you happen to find one in good condition. The 216 THX should be great as well.

I would suggest if you do not use Room correction try it for instance Mathaudio room EQ in combination with Foobar2000 for free. Buy a measuring mic do some measurments an compare how your NAD speakers sound with an without room correction. Go from there. For me it was an eye an ear opener i even did not needed any subs anymore. As an example my close monitors (IMF Compact II). Grey line is found frequence respons white line is (my prefferd) flat corrected sound.

NAD has a very good rep - I still have my old NAD 2100 amp in my bedroom system.

Nad 3020 and 3130 here. I really like the phono section from the 3130. I do not care it is good at measurements, it's just the one I've learn to listen to records. So I love it and still use it (from phono to REC out to the amp). Never ending pleasure!

I've seen a lot of website selling parts to change caps and other few components. Surely a nice project for this time.

I had a NAD 7140 in high school and college. My mom traded me my 20-watt/channel Pioneer SX 535 for it because she liked the silver more than the black. It wasn't a trade I resisted. That thing was ballsy and sounded great. I spent hundreds trying to keep it alive after I graduated college, but it kept on failing at that age.

Here's an interesting review on it from the time (Not vouching for the testing.):

"The Model 7140 distinguished itself in these tests. Not only was the 2-ohm clipping output a full 98 watts per channel at 1,000 Hz, but with the 20-millisecond tone bursts of the dynamic-head-room test it produced an astounding 233 watts per channel! "
