Ready to move onto next stage of streaming

I'm new to digital and am building my first dedicated listening room.  I purchased a NAD M12 w/ BluOS module and M22 v2 combo.  Connected to the M12 is a Mac CD player, Techniques SL-1600 MK turntable, and Squeezebox Duet,  I stream Tidal using BluOS from a laptop and sometimes via the Duet.  My CD collection is ripped to a Synology NAS, I use Logitech Media Server to access my digital library via the Duet.

With Tidal, I've noticed that not all MQA & FLAC music sounds that great with my setup.  Most jazz which is what I care the most about, sounds very good to awesome.  I'm an oldschool R&B guy, and most 60's - 80's music sounds pretty good, but not as good as more recent jazz music.  

I've noticed that some transitions regardless of genre, are rather "explosive" or bright, by that I mean get too loud at their peak or the highs just appear to be too high.  I can play the same music on my analog Mac system and different speakers and don't get that same effect.

I don't know if its the NAD DAC not being able to handle that well, or just digital in general.  My NAD gear is only a couple of weeks old, so I'm hoping things will improve over time.  I also have to add acoustic treatment, which I know will help.  I've budgeted ~ $1500 for that.

I'm retired, and trying to stay within my budget.  I just ordered a Furman Elite 15PFI power conditioner and I will order a better power cable.  I use AudioQuest mid-priced interconnects.

Any advice would be appreciated.  

I can concur that not all MQA&FLAC files seem to be created equal as far as Tidal is concerned.
I am not sure anything inherently wrong in your system, I experience the same at times although does not seem to be rampant in my area of predominantly rock and modern rock music.

You will likely notice a decent drop in the noise floor with the addition of your Furman and a good pc never hurts!

Nothing too much wrong with Audioquest stuff, even the budget stuff is fair.

Welcome to the world of ever decreasing circles on tweaks!

uberwaltz,

Thanks for the response.  While I'm looking forward to making incremental improvements towards my version of a "perfect" sound, at my age, I've learned that somethings just have to be good enough.  

I like what I have so far.  The only other piece I may buy is the NAD 50.2 so I can put my Mac CD changer back with its brothers & sisters in my man cave :-)

The NAD M50.2 does look like a very nice piece of kit although full msrp of $4k is a bit steep. Seen refurb ones closer to $2500 which is a lot better.

@uberwaltz,

I find myself in a similar spot. I, too and using a Lyngdorf 2170, but with a BlueSound Node 2. Also using a digital coax cable between the two. It sounds good, but am wondering what it takes to get to the next level (maybe a lot of $$$)? I am new to the audiophile world and the Agon threads (low experience). With that said I have already read plenty of battles on cabling. I'm not trying to be controversial or looking to start a fight, but have read that the Bluesound equipment responds well to power cords and digital cables. I currently use a Cerious Tech digital IC (sounded better to my ears than my previous BJC) and a Pangea C7 PC. Also, kind of sounded a bit gimmicky, but have read some positive user reviews about the iFi SPDIF iPurifier and am contemplating giving it a test. At $150 and the ability to return if it does nothing are appealing to me. Good luck!
