Newbie want to improve what I have

You could have done a lot worse. Hard to make suggestions but tell us about your room and speaker placement. 

Wire is not a tone control. Stick with what you have.

Nothing wrong with your choices! I presume the M33 is a streamer/DAC/amp? Then you are limited to the streaming services' music offerings. You don't know what mastering variation was used. Some are better than others. That is why I prefer to own physical copies, LP's and CD's, so I can choose the best versions.

you have learned the hard way about system matching

 

did you listen to the combo or did you order everything and are now listening to the system

 

the nad m33 is an excellent amplifier but it is too clean for the sopras you need a warmer amplifier 

 

you have two options

 

1 sell the m33 and move into a warmer integrated amplifier

We are a focal dealer the Unision research unico 150 sounds amazing with them

 

or keep the M33 and use it as a streamer/preamp and use a warmer power amp

Congratulations. Nice speakers. NAD is a brand many people start with. Good start.

If you have just completed assembling this, you may not want to swap boxes yet. You want to become very familiar with the sound but aid with cable choices like you said.

So, it makes sense to warm it up. You want to look at Cardas cables and interconnects. They are specifically designed to be warmest at their most budget oriented levels and to become more neutral as one moves up in their lines. This is what is typically needed as you move to higher level components.

Early on in my audiophile career (~40 years ago) my system was too bright and Cardas Golden Reference did exactly that. These were high end warm cables they used to make. Anyway, years later I made a big upgrade and I immediately pulled them off and moved to more neutral wire. You are thinking correctly. If you can get it sounding warmer, then you can really work to position it correctly and tweak it, and fix up the room. And it becomes your reference for a few years until you choose to upgrade.

When you choose to upgrade. Most of us have individual boxes for streamer, DAC, preamp, and amp. The more boxes, in general the better things sound. Each is optimized and isolated from othe functions. If that simply doesn’t work then a streamer / DAC and an integrated amp. Can work.

Also, setup and room treatments can make huge differences. There is a place to show photos your system and venue. We can be really helpful if we can see your system. They need not be show photos. You can see my system under my UserIDs.
