I wanted to get a pair of stock Spire's here when I completed these but understandably the dealer then was not at all interested in it! But yes Justin it would have been good to compare the two side by side for sure. I did think that the speakers were good to begin with though, and "worthy of some small changes" I thought back then
though each time I have heard stock ML's since, either Summit, Summit X, 11a and 13a, Montis, the tranparency wasn't anywhere near the same, and the bass in mine is far less bloated and more controlled and reveals tone better. Just to point out though that the 10" bass unit is still mounted in the original placement below the panel, with only the electronics and crossover moved to the external cabinet, which may get a rebuild at some point as these are not quite truly finished. These run off the Symetrica too which is a must. Early experiments with Bal power was only on the speakers years ago when these ML's were stock, running each speaker from an airlink transformer and that clearly demonstrated that it worked but they did hum a bit, hence using the big DC filter now in the Symetrica.
The marriage of the CF ZL-200 mono's and these does work very well though as these dip to below 1ohm at hf, so clearly the amps can deliver the current required from just 8 Mosfets per channel in BTL configuration. This can give amazing power and dynamics and often provokes a '**** me' moment.. I wish there was more talk on here about ML's, and Marc, I didn't realise you heard the Neolith unveiling, was this at KJ? To hear that these surpass that set up is a nice thing to hear! Thank you! Fwiw, I put the Neolith as a choice on Davey's thread along with the Nautilus which I'd love to try here if anybody has any kicking around? lol..
