Upgrading pre amp advice.

Work on tweaking your speaker setup before doing anything else.  It's free, and as other posters have said, save up for something that will actually be an improvement over your Bryston (which is already good gear).

Buy a great preamp, it's the heart of your system...   It's the one piece I have historically spent more than I budgeted for every time.  .   

A great pre can really elevate your system, a not so great one can be the bottleneck of an otherwise excellent system.  

I wouldn't hesitate to recommend the Musical Fidelity Ms8pre  , I have it mated with an Jc5 Halo and also tried the Ayre K-5xe- mp and JC2 bypass . The MS8pre just ticked all my boxes and sounded phenomenal! 

My "advice" is to buy an Audio Analogue DAC for $5k with an analogue volume control and pull out your preamp and its interconnects(and sell it all!) from the chain. 

A DAC with a very good analogue volume control removes the need for a preamp, which is basically an expensive volume control that adds its own characteristics. 

That's what I'm doing with a Playback Designs DAC.

So I can’t offer a straightforward amount. 
Here’s some background.

my starting point was an Auralic g2.1 streamer feeding a Sonnet Pasithea DAC using the DAC as a preamp. I actually really loved this combination. But then I went crazy and wanted to add a turntable to the mix and the DAC only had digital inputs so I needed a separate preamp. That’s when I tried two separate preamps in the 3k price range and was not happy with either. Felt like I was going backwards.

in my exploration for a third preamp I read some great reviews of the Grimm MU2, which would replace the Auralic , the Sonnet, and provide what people said was a fantastic analog pre, and so figured I’d give that a try.

turned out I agree wholeheartedly with all I read and this was clearly a step up in my overall listening experience, but it was also a price increase that felt really had to swallow at that time.
