Please help me!

You sound like a particle in a box.  relax and slow down.

My only real comment is that the cheap power conditioner is not suited to power your amp.  test it plugged into the wall.

And remember, the human mind can interpret "different" as "improvement".  Do A/B testing, back and for for several hours, before you conclude that the different sound is actually better.

Sir, by your self description you would be much better off with a solid state integrated that has tube characteristics like the Pass Labs INT 60. Team this with the Harbeth SHL5+ loudspeaker and you with have the system of your dreams. You will also need speaker stands. The tweeter should be at ear level when you are seated at your favorite position. Tubes are NEVER as simple as solid state amps as they always need to be changed lasting at best a few years. Many go bad in only a few months. They can be very unpredictable.  

Don't sell anything. Your gear is not the problem. Check your cartridge stylus and alignment from time to time though.

Your room dimensions, 10' by 10' is a problem (modal hell and reflections). When spurious reflections/relective sound and direct sound arrive at your ears too close in time, it will fatigue your brain. Room modal resonances can cause fatigue over time.

For now, move your listening seat close to the speakers and try listening in nearfield. Adjust toe-in angles. Start treating your room (room treatment).

Man's innate madness, endless ignorance and arrogance  will make him pray for anything and everything, as you may know. However, this planet is quite fortunate that most prayers in this world go unanswered. If every guy's prayers were answered, the planet will just cease to exist and humanity will end. 

So, please don't ever start praying for me man...thank you.  You could pay for my lunch at a cheap restaurant though (mapo tofu with pork and rice).

I recommend you set your system up in a rectangular room. Your 10 feet X 10 feet room will have incurable bass resonances that will muddy up the sound. You could remove one wall.

Why spend thousands on an integrated amp? For $249 you can buy a pair of Fosi V3 Monos with the 48 volt power supply. Add a $149 Schiit Mani 2 phono stage and you will have a combination sonically better than any Luxman!
