The problem is the Clearaudio uses spikes, which is not very good (read, any) isolation from the Delos butcher block. The solution is replace the spikes with three Townshend Pods. Your turntable at 24kg would use 3 Pods, 8kg per Pod, that would be the size C Pods, green on the chart. http://www.townshendaudio.com/hi-fi-home-cinema-equipment-vibration-isolation/seismic-isolation-pods... These are the same ones I use under my turntable, and the improvement is obvious. Besides dramatically lowering the noise floor there is a distinct improvement in clarity and much more tonal or harmonic truth to instruments. Bass is greatly extended and tighter. Jut a huge improvement.
Two other guys with similar issues PM’d me and took my advice, with the same great results. I know that’s the right size from doing mine, but never hurts to give John Hannant a call, just be aware the Pods work just as good under amps too and so it may prove to be an expensive call. But then again to transform your system (which it will, it has mine) well worth it.
