Thanks for the invitation maybe in the next couple of years I may make the pilgrimage to Salisbury (not stonehenge) if so I will take up the offer.
When Ivor Tiefenbrun visited our Hi Fi store in Brisbane (25 years ago) we were comparing the Linn and IIRC a Technics SL1200.
Both turntables were equiped with SME 3009 and Ortofon M15E Super cartridges but the interesting thing aside from the different sound was the power output.
The amplifier was a Luxman 150 watt per channel unit that had VU meters, when playing the direct drive the average power delivered hovered around the 50% with peaks of 75% full scale deflection. With the LP12 the average power was more of the order 25% with peaks of 100% full scale deflection.
Ivors explaination that the direct drive with the acoustic feedback in the aluminum platter and base and motor subsonic rumble etc. was being amplified robbing the amplifier of transient power and generally working hard all the time.
Mick this is a test worth trying, I would be interested in the outcome, in the meantime don't disregard the tar, this mixed with sand etc.
Regardless of how good the Loricraft base is taking the ring out of the base first will improve the performance, test the base by tapping it during playback and observe what comes out of the speakers, don't forget the sound from the speakers is impinging on the aluminum casting base and platter.
Don't loose sight of the fact that the ambience adored by the valve enthusiasts is in part due to the microphonic nature of the output valves, producing the ambience effect tapping these will also provide the confirmation.

The reference to the Dual etc. is that they also rim drive turntables, but you have recognised that, OK it rumbles but for 16 quid what can you expect - it is excellent value for money.
Whilst the geriactric LP12 is the same age as the SP25 nobody then or now would consider these units remotely equal but the Garrard SP25 is significently superior if value for money presses your button.
It is worth noting a lot of people are enthusticatic about another geriactric product of 25 year vintage and that is the NAIM NAP250.
And on a similar note even older Marantz 9 and Radford ST25 still command respect.
There is no question that the LP12 is dicky to set up, but there is nothing magical about this just common sense, here is a clue cut 3 x 60mm holes through the base below the springs and the spring height etc. can be adjusted without removing the base.
Final test - if the tunrtable feeds back then the setup is crap.
