HIFI Advices please read

^ Nightfly....I would think about upgrading the speakers first and try to allocate most of your budget there. That Audiolab 8000A is a pretty nice amp and I believe will drive 4ohm speakers......Now Tannoy's are pretty nice! So unless for some reason you want to change those that's where I would start. All your gear is pretty decent stuff honestly.....If all you want to do is upgrade the sound, look into an external DAC, especially if your CDP has digital outs, that will improve the sound of your CDs quite a bit. The Grant Fidelity TubeDAC11 for USD350.00 is an amazing DAC that performs at 2x its price..I have one and its brilliant!

Pre-amp and Speakers? My accepted speakers are a Bose arrangement with the Acoustimass bass bore and bifold hinge cube speakers.....I absolutely adore the complete actual abundant and additional with the cube speakers getting that they are about 8" alpine I can abode them anywhere in the allowance if I wish to change complete quickly....I do accept them on pole stands.

This is the nice dack..
Looking like very old but nice one.

Ummm....vinyl sounds better than CDs...

Putting heavy weight also lower the unwanted vibrations produced by the sub, a second effect of that upgrade. Rather than smoky theories and formulas, the best is to try and listen. Because we don't listen to theories but to sound. Nah, you cannot prove that  is the "a second effect" - if (as you say) that adding the slab of marble on top of your passive pre-amplifier affects the sound you hear then that 'improvement' is in suppressing the primary source of unwanted noise, which would be the rattle of the pre-amp casing caused by the proximity of the sub woofer and not to any 'theoretical' yet completely undetectable electromagnetic inductions into the electronics caused by the vibration (which is what you have claimed is the first effect).   I also question the use of an acoustically resonant and very reflective marble slab here - this is not just smoky theory, this is supported by practical observation - take a sound source into a marble/ceramic bathroom if you want proof.   And none of that is smoky theory and formulas - that was all derived from practical observation and a practical knowledge from years of experience.

I have yet to discover any difference between theory and experience in the realm of hi-fi electronics and audio acoustics. My 40 years of practical experience in applying theory into practice has taught me to question, analyse and understand cause and effect - nothing happens by magic no matter how hard you wish that it would, acoustics are not governed by the supernatural but by very basic physics that is taught in school rooms across the planet. Ignoring the 'theories and formulas' does not make them go away.

I mean I doubt I would notice but maybe high-end audiophile, tubificational type amplificational system would actually amplify the different "colorations"........so to speak

That one is simple to prove or disprove by practical experiment: disconnect the cables from the left speaker and play some music - any sympathetic vibration (hell, any vibration) in the left speaker cone will produce an electrical signal across the speaker terminals that can be measured on an oscilloscope even if you cannot physically see (or feel) any movement in the cone itself - the difference between a speaker and a microphone is simply size. How big that induced signal is will determine how much of an effect it would have on the left channel's sound/colouration.
