Brightness


Hello Friends
Hope some can help?
my system is 
1. Well Tempered Classic, with Marigo cup upgrades, this is fed, to PS Audio, Gcph phono stage!!, I have it as comes with volume control, fed to my MonoBlocks, I have a PS Audio, pre/dac, pre amp, that I can connect, to play CD/s, which I have not done, in the last 5 years, or connect phono stage, to the preamp!!
I love the "Bass"", no need for a subwoofer!!
But why is the treble, is over harsh!!
I think, it may be  the pre amp??
Or is it my speakers, which are Zu Audio Souls M2, to much wizz??
I was thinking, may be to buy, a full tube "icon audio" PS2 phono stage, with volume dial, to send to my mono blocks??, but it seems to me when you go to valves, it does not go down with with deep bass , and slam??
Reason for the above, I live 3 hours drive, from a decent, audio shop!!
So I'm all alone, to make a choice??
Please Friends
Can you give me, your thoughts
Regards

It is unclear whether you have the same brightness with CDs and with LPs. Let's start there.  Next, has this always been bright? Or, has something changed recently?  If so, what component change did you make that might correlate to the brightness?
You need to be logical.
Also, what recordings? Sadly, most modern rock recordings are bright.
So let's break this down logically and isolate what' what.  You can get good sound from lots of components. randomly swapping in megabuck products is just silly.
BIG 2nd to what Eric wrote about rooms. reflective surfaces can create horrors. Like i keep saying:
1. room2. setup3. source material
actual electronics are further down the list of priorities.

Dave, What is your preference to play? Vinyl? How is your TT set up? You mentioned you hadn’t played a CD for five years, so we can rule out play back from those. Do you stream? If so at what resolution and via who? Ethernet or Wi-Fi connection?
Dave, to help, a bit more information would be appreciated if possible.
