Had you ever tried the DAC2 module in your VR L2iSE?

I was on the hunt for an external DAC upgrade thinking I was missing something with the VR DAC 2 in my own L2iSE. The recently referenced review on Audiophile Style comparing the Rossi L2iSE (DAC2) with the likes of Chord Dave convinced me to end my search. Seems that there may be limited or minimal improvement by throwing multiples of the cost of the VR DAC2 for an external solution. 

I agree with the review that the combination of the internal DAC2 with DHT tubes and internal Mosfet amp creates a synergistic solution that eliminates costly additional peripheral interconnect and power cabling. I'm feeding my L2SEi DAC2 via USB from the Antipodes K30 server. I did find, however a noticeable improvement upon the addition of a Shunyata Omega USB cable. Also, I do have a costly power system consisting of Ansuz C2 level power distibutor and cables.

At this moment I'm enjoying and appreciating this system as the Nenuphars (with additional run time) continue to reveal more and more musical nuances. I would be interested in trying some Silversmith Fidellium cables. Anyone experience these on the Nenuphars?

@dspringham Hi Dave.  Yes, the DAC2 module for the VR L2iSE was one of the first I compared to my Totaldac D-1 Dual.  I found it to be surprisingly close in sound (especially for the $$--the Totaldac being about twice as much), but the Totaldac was noticeably more open and alive.  They're are some other notes I have on the comparison if you want to PM me.

My current favorite is NE Eno series. They bettered the Sablon in my system. The NE has a new reference model Muon which is more costly but I have not heard it.
