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.

I'd remove the NAD 326 from the mix. The right amp will make a world of difference. I'm so impressed by my most recent purchase of a bipolar Adcom GFA-5002. Heck of an amp! The 5XX series of older Adcom amps were bipolar as well as I have read. Adcom still makes new Bipolar amps. You should be able to resolve your very slight brightness issue w/a different amp/pre-amp/int. amp. Good Luck!
Since you built the speakers I would take the easy and least expensive step. If your tweeter is too hot, then replace the capacitor with a nice PIO type that will do wonders. I suggest Jupiter HT Flat Stacked. If you also have a cheap sand cast resistor, replace it with a Mills MRA.

This will do the trick. It will make you smile!
I would be happy to help if you need direction. This will impact your system more than wire or an amp change and allow you to keep your speakers.

It will not require you to buy, sell and ship gear.
Your speaker uses Dayton caps and resistors....oh yes the mod I mentioned above will do wonders!
Very good advice above, particularly from Kiddman nad Grannyring. Given that the speaker is something of an unknown element, it is a prime suspect. Also, different model speakers vary much more in sonic characteristic than do any electronic component. You should check it out by making direct comparisons with other speakers. If the problem IS with the speaker you should really consider dealing with the problem by either replacing the speaker or modifying the speaker before considering chasing compensating with other component choices.

Any extreme effort to compensate for a fundamental imbalance of flaw in one component by choice of other components will be a big waste of money and is not likely to work. Components may subtlely complement each other, but, they cannot correct for weaknesses of others.

It is understandable that you have a fondness for the speaker you constructed. That is why Grannyring's suggested crossover upgrade is a good first attempt at curing a problem if it turns out that the speaker is the primary source of the problem. This is a not too terribly expensive approach and you can go back to the original components if the modification makes matters worse.

Before doing anything at all that involves spending money, try changing speaker placement or moving the listening chair. Tonal balance can be changed quite radically by placement changes and there are infinite choices one can experiment with. With most speakers, the easiest way to change upper frequency balance is to alter toe-in of the speaker and the backwards tilt of the speaker. You could also try some simple room treatments to tame excess reflection of higher frequencies (e.g., put up tapestries on the walls).

Good luck.
