Current NAD integrated amps, what are your impressions?

I just picked up a C326BEE and wanted to hear if my results are common, or what the general consensus is for NAD. I did some searching on this forum, but there doesn’t seem to be a lot of love or threads directed at NAD.

I actually acquired a C372 about 3 years ago, but sold it within a year as it seemed pretty bland and laid back. I’ve heard that this vintage wasn’t as reliable and my remote control did die. When I shipped it to the buyer it showed up DOA in one channel! I helped him with the repairs but it left me with reservations regarding NAD. From what I can gather, the current models are much more reliable.

So Spearit sound is clearing out refurbished NAD components, and I couldn’t resist the price(no affiliation). Bottom line, the 326 sounds way better than I expected. I’d been using a Denon AVR3801 in 2 channel with a second system, and the imaging, clarity and punch is easily better with the 326. I’m driving Tannoy DC4 bookshelf speakers and what a soundstage!. Diana Krall tracks are recorded with the piano mic’d so the lower register starts in the left speaker and the highest notes in the right. I’d not heard that with the Denon, but the 326 sets it out so clearly.

So what has your experience been with NAD?

I ended up buying from another retailer that has a BNIB 375, and I'm sure it'll sound at least as good as the used one I returned.  One more thing on the comparison between the 356 and 375 as I compared them one more time before shipping this morning.  The 375 has a smoother top end.  The bass of both changed somewhat with the PS Audio AC5, accuracy became better for both, but the AC5 takes a while to break in, over 200 hours or so.  

So now I'm back to the 356 for another week until the new 375 arrives.

The new 375 finally came in and I've been burning it in.  Over the previous 375 that was several years old, the new one has finer volume adjustments with remote control operation.  I also find I don't have to use the adjustable gain outputs on the pre section because the output steps off 0db and ramps up more gradually, if that makes any sense.  

Quite a nice improvement.  I'm not doing any careful listening just yet until I've got at least 50 hours on it, but I do notice refinement and it runs a little warm though I'm not pushing it yet by any means.

I look forward to your report. I just received a 356BEE yesterday and will check it out today and report back as to what I think compared to the 326BEE.

Okay, I'm about 25 hours into the break in.  After about 6 hours, things started going south on the sonics.  A further 10 hours or so and it stared coming back.  This is leaving the unit running for a max of 4 hours at a time, and then shutting off for an hour or more, to run again the next evening, or longer on the weekend.  I didn't want to leave it on 24/7.

The other thing is that I'm breaking in the PS Audio AC5 power cable at the same time, so I'm not sure what exactly may be causing the changes in sound.  But at 25 hours it's getting pretty nice.  I read where another 375 owner was told by Nad dealer that he should break it in 100 hours, but we'll see what it's like at 50.

Well, I compared my 326 to the 356 driving a pair of Esoteric MG-10s in a 12x15' room. Not surprising they sound more alike than different. I agree that the bass might be a little tighter with the 356.
I do believe that for my outside system I will like the added power of the 356, having somewhat less strain on the amp at loud levels. Don't believe the 356 would hold much advantage over the 326 when paired with the B&W 685s (or other speakers representing a similar load) with system placed in bedroom size room. This statement based on retail price. 

Next sunny day, I will take the two amps outside for a walk with the 685s and possibly the MG-10s.
