I haven't really set a budget, not in the sense that monies no object, but more when something comes along suitable at a decent price I'll go with that.
There to go in a system comprising of some B&W 600 series S3 speakers so something of the same calibre really.
I printed out Hoffmann's arc protractor and aligned my cartridge with it (an easy task). The dealer who installed and set up my turntable (Michell Gyro SE with TecnoArm) came around with a Dr Feickert device to check the alignment and found it to be spot-on. Neither method gave the same result as a conventional 2-point protractor.
Just a few things to think about here before putting insulation in a suspended groundfloor. By introducing insulation it alters the location of the dew point ie where moisture vapour from the house will condense. Therefore if you are considering putting sound or thermal insulation in a suspended ground floor you should also put a vapour barrier above the insulation (ie just below the floorboards). If you so not do this you could get condensation either part way through the insulation or under it. Also, rather than wires etc to support the insulation it is easier and better to use something like garden netting to support the insulation.
For sound insulation between the joists on upper floors then something such as Rockwool Sound Insulation Slab is good. This can rest on the ceiling below but if you are worried about the strength of the ceiling then again the netting can be used. Ensure though that the slabs fit tightly between the joists and between each other to get the best effect. If you use the Rockwool Sound Insulation Slab on a suspended ground floor for sound transmission reasons then also think about using a vapour control barrier because even though the Rockwool Sound Insulation Slab is not primarily a thermal insulation slab it will have some thermal insulation properties that could otherwise start condensation either in the slab or under it.
Wickes and others sell these.

Interesting! Though 3-5mm difference seems hell of a lot. Not surprised it made a difference esp on the 12".
I had a loan of a Dr Feickert to check my alignment and it was spot on after using one of the universal ones. Must give it a try though, at least as a check on what I have at the moment.
There is significant Impedance missmatch then. Fit a buffer to your passive.. It works !
Nichion Caps are "at least" as good as the Arcam OEMs
Be prepared to fit fresh diodes when you replace the Main Filter caps The Fresh caps inrush currents will over stress/fail aged Diodes.
