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 have 2 NAD integrated, the C326BEE and the C372. The older 372(7 years or so) is warmer sounding than the 326, yet I wouldn't call the 326 bright. I have Paradigm S6 speakers with forward sounding tweeters that make some amps sound brighter.

I had this struggle that you are having as well. Your speakers with the ribbon tweeter are going to be brighter sounding, and with your preferences you are going to need to compensate for this. Something that helped me is better cables. What kind of speaker cables do you have? If it's just basic stranded copper 10 or 12 gauge, I'd suggest Audioquest Type 4, you can buy it in bulk per foot. It really brought more focus and clarity to the sound, something I was really surprised about.

Rather than trade up components as I did several times, your issue might be easier to fix. The NAD isn't bright, neither is the Onkyo. Just a thought.

I am still curious on one point... When considering amps and preamps, does one have more impact than the other on the sound we hear? Or are they equally responsible for the end result?

I feel that the preamp has more affect on the sound that we hear than the amplifier, but I'm sure others will disagree. You could always try a tube integrated amp in place of the NAD, in which case you could get the richer tube sound, as Atmasphere suggests, and not worry about the which component does what conundrum of preamp or amp.

One further thought. The speakers in this set up could be a difficult load. Any idea what the ohm rating is and if it dips lower at certain frequencies? It could be a tough load for a near entry level integrated amp. If that's the case, at higher volume levels it could produce a harsher sound.

A Tube integrated would certainly be warmer too.

try some solid core 12 gauge mains wire from
Home Depot for the speakers. And dump any
cheapo interconnects.

I also believe that the preamp highly affects the color or timbre of the system.

BUT, as Runnin points out, it is the amp that drives the speakers. The first part of putting together a system is matching the amp to the speaker, and since your spkrs have a low impedance, you may need a more powerful amp.

The resistance curve found on the left side shows that impedance drops to 3 ohms at 100 Hz and approx. 4 ohms from 1K to 4khz.

The specs on your amp show:
- 2 x 50W Continuous Power into 4 ohms and 8 ohms
- 100W, 150W, 200W IHF Dynamic power into 8, 4 and 2 ohms, respectively

I am not familiar with the design of the NAD, but it looks like it may possibly be enough power, but borderline IMO.

What do the other NAD owners think?
