Just a bit to bright


Hello,
I've been listening to my entry level system for almost a year now and while overall I am happy with the sound quality, it sounds just a bit too bright at times. My components are an NAD 326BEE integrated amp, Onkyo C7030 CD player, Sonos Connect for streaming Spotify, and Speaker Design Works MiniStatements speakers.(DIY)

I have not noticed any significant difference between CDs or streaming music sources so I feel like if I wanted to find a sound that is not as bright, I need to consider changes at the integrated amplifier. Since I built my speakers and feel proud of them and their sound, at this point I'd like to try and find the sound I'm looking for with these speakers. I do understand, it is possible that someday.... they may become a component that needs to be changed.

So my thoughts are, try a different integrated amp, try a different amp and use the NAD as a preamp, find a preamp and use the NAD for an amp, or try a class d audio amp... claiming to have a warm tube like sound.

My question is do I just need to jump in and try one of the above?

Which component (not the speakers) would likely have the biggest impact on a system that is a bit too bright?

Any suggestions would be greatly appreciated.

Lots of poor to average recordings and that cannot be avoided. The mod with the Jupiter caps will also help those. Yes, play with toe-in as well as sound absorption panels at the first reflection point.
Thank you for all the replies!
Lots of great food for thought which is exactly what I was hoping to find here.....
A couple small bits of information:
My speaker cables are 10 gauge, 462 strand OFC
Interconnects are AudioQuest G-Snake
My speaker sensitivity runs about 85 dB (@2.83V), if you adjust for a 4 ohm load they're around 83dB (@2V)... Based on my test results using the 1 watt, 1 meter distance standard.

I have a few friends that would likely allow me to try an amp or place my speakers into their system and look for the brightness to remain or disappear or...

With regard to toe-in, my speakers are designed with a mid transmission line/pass through.... The mid-range driver has an open tunnel to the back of the cabinet. They should be placed 18" inches from the back wall and with straight ahead positioning. They really do offer great imaging with vocals in particular.

I'm really intrigued with the idea of swapping out some of the Dayton components! I built the crossover boards in a way that provides easy access and removal, so Grannyring, I may take you up on your offer of help.

I've also been exploring an amp by Class D Audio. Reviews state it has a very warm tube like sound. With 250W @ 4 ohms I suspect it would drive my speakers well. But... I won't be pulling the trigger anytime soon. I've got homework to do.

Patience. I've put my wallet away and will continue exploring the simple and inexpensive adjustments.

Thanks everyone!

This statement may give a clue to the problem here. So whether you have a 10 foot long room or a 100 foot long room, they should always be placed 18" from the front wall? I don't think so! The amp might be a problem but not the first problem you should deal with.
Have you experimented with the difference between bi-polar outputs vs. mosfet outputs? I mean even to audition? Your NAD will never satisfy you. It's simply not high enough caliber given your op. There is a marked difference in general between the two. Mosfets are softer on the top end, however, really good bi-polars make no apologies. They are faster. But I'm convinced you really just want something better than what you've got. You really are still at square one in terms of what topology pleases you. An excellent bi-polar example would be the Harman Kardon Citation 16. A legendary amp which is imo second to not many sota amps even today. It came out around 1980. A competitive mosfet amp would be an Acoustat TNT200 or 120. Same era. Both are still highly sought after. The newest HK offering apparently has the same basic circuit as the 16 which is in itself revealing.
Great advise from Kiddman. I often wish I had learned that lesson much earlier in my "audio career".
