@bluemoodriver, the DBT you posted is hysterical. Between the "high-end system" and 5 dudes in the sweet spot, you're really making quite the case. I can't believe they weren't able to tell the difference! LOL
I know! It is surprising isn’t it.
Cheap cables tossed over a chair. Basic receiver. Sounded just as good or better than the much more expensive set up under blind conditions - as long as the room and speakers and source was the same. (They didn’t all stay in the room for the listening tests of course).
Reassuring though, isn’t it.  
Musical fidelity is not the same musical fidelity, as the company was sold. Despite this, they still put out decent products. I own quite a few of their "small box" products, such as the v90 dac...good stuff...

-The respected British hi-fi manufacturer Musical Fidelity is now owned by Austrian company Audio Tuning Vertriebs GmbH, which also owns Pro-Ject Audio Systems, and the new owner has assured audiophiles that the future is bright for the iconic British brand.Aug 9, 2018-

I agree with above statement. Change the preamp first. For tubes I would go with Rouge RP5 or RP7
RP5 has phono stage
RP7 no phono but fully balanced
or
Hegel P20 or P30 for solid state. Everyone wants to change the amp but their missing the big picture. My local shop that sells both. https://holmaudio.com/
Also, 
Change you power cord on your amp from the stock to a 14 AWG or 12 AWG cable
