This is a system I have accumulated over the last year having changed from an audio research based system which I enjoyed for many years to an art audio based system the focus point of which is the diavolo amp. I replaced my hales speakers with the Tetra 506 lmtd these speakers were the ones reviewed in the online magazine tone and took this system to another level. At this point I listen primarily to vinyl and at some point will probably upgrade my tt. Any advice or input is certainly welcome!
