Chaps, Time has come to make that sub purchase. I am completely sold on the Velodyne series, silently following the power buy threads for many weeks. I had made up my mind to buy the CHT-15, even so far as mailing eric, however I am now not so sure. Has anyone heard back-to-back or otherwise each of these three monsters and can give a definitive opinion of the differences between the beasts. Is the HGS-15 worth a grand and a bit more than the CHT-15 and then if one sways to the expensive, is the difference between that and the almighty HGS-18 worth digging just that bit deeper for the extra few hundred ? I know that all posters are happy with their respective purchases, and I have yet to read A SINGLE disgruntled thread, but has anyone heard all of these beauties in action ? My system is reasonable high endish - TAG process and amplification, and ProAc front/centre speakers. I want something MEAN Any opinions ? Regards.
