This is the Ultimate Reference model from Lampizator. I have reference level Tubes as well. For those who know me, I have seven 2 channel systems in my home and a full theater. I have and have owned many of the top brands in the world. I still have 5 all out assault systems in my home and about to take the assault even further thus it means I have to make room Lol. For sale is one of the best dacs in the world. Please look at all of the reviews. It is of course in great condition. Unfortunately I only had a chance to hear them for maybe less than 15 hours since I have owned it. It just was in my family room thus the room I use the least for music. So it is a waste for sure. I am selling that whole system that includes the top of the line Robert Koda preamp and Dynaudio Evidence Masters Steinway Edition. I have really been unfair to that system as I have really less than 20 hours on it since I built it. Thus, now I am already moving on to another system for that room. My loss is your gain Lol. If you are interested I will facetime with you and show you the system and whichever component you would like to see closer. I will only take Paypal friends and family or wire. I would prefer local pick up. If you do so, I will give you an even better deal. I just want the convenience of no hassles to be honest. Not a money thing for me. This is one of the most rare items on market.
