My DI's are sounding better everyday with about 150 hours on them. I find these speakers to display some of the finest sound reproduction I have ever heard and most definitely nothing touches them at this price point. I have some nice maple speaker stands coming and I believe that will tighten up the bass some from previous experience.
I am using a new Modwright Oppo UPD-205. and i'm sure the modded output stage is partly responsible for this glorious sound I'm getting. I have some CD's and blu-rays but for the most part I'm streaming via Ethernet from a dedicated server upstairs using jriver and jremote app.
I'm still using only the LTA Micro ZOTL as my 1 watt amp with no preamp in between. I am waiting for Mark Schneider's next creation. I was at LTA recently and listened to a low watt prototype and was impressed.
In a couple of weeks I will bring my ZOTL40 downstairs to try out with the DI's. I have some exotic tubes including NOS Mullard EL34's and EL38's with adaptors. I will report more on this later.
I am not ready to suggest that the DI's best my Janszen zA2.1's and they of course cost 4x what the DI's cost. I worked long and hard to optimize them in a small dedicated room. They did not fill this basement room with sound as well as the DI's do although, so room dimensions matter.
