Default Output trans plate load question 5687 vs 5965

I'm building a pre-amp with 5965 tubes. I have some output transformers that I believe were built for 5687s. I have no way to test the trans to know.

Since the plate resistance of a 5965 is ~7000 and the 5687 is ~3000 what will that translate to sonically if I put a 5687 optimized OT on a 5965?

At the moment I have the circuit optimized where everything is sounding beautiful save for issues in dynamics such at impact, speed, attack and weight.

I'm wondering if I'm fighting the OTs?
