Is there any benefit for adding a preamp for my current system set


I have a MHA 100 headphone integrated amp that is rated 50W 2x channel running to pair of Soliloquy 6.3 speakers..
I’m bi-passing the built in MHA DAC and connected amp to a PS audio direct steam Dac w/ bridge II.
To my ears, the system is satisfying.

My question, would adding a seperate pre-amp between the DAC and the AMP create better sound? I don’t necessarily need the extra pre-amp inputs for now, but would consider buying the pre-amp now if noticeably affected the fidelity. Thoughts, thank you.

That depends on the functions or features that the preamp is able to provide. I would say no, for now. The best way to run any system is with minimal colorations in the sound.
Short answer is yes, active preamp might give you a better sound. Interconnect cables between preamp and amp would also be very important, they should not be lesser than cables between source and preamp.
What exactly do you like about the MHA 100? You already aren’t using the DAC and now want to skip the pre as well. If you decide to use a separate pre then you’ll still be running through the MHA pre section if I understand the unit correctly. If instead you used the pre out on the MHA into a power amp you would avoid redundancy. I’m not saying a preamp won’t help. There are as many exceptions as rules, but in general, extra stages of gain and attenuation are likely to do more harm than good.

I’m not familiar enough with what you have now and what you’re looking for to gauge what type of improvement you’ll gain or even what your budget is. Give it a think and make a plan. Even if you can’t buy it all at once, at least you’ll know where you’re headed.
