My first Raidho's were the D1's driven with an Octave V110 tube integrated with a black box. The Octave sounded great with the right tubes. But before the D1's I had Dyn C1 sigs which had deeper lows. I thought I could blend in my Rel B3 but it didn't work out too well for me. Later I finally upgraded the D1's to D2's. No need for a sub anymore. But if you pushed the volume to the max the tubes ran out of steam especially in the lows. So I got the Aavik that was used at the 2015 Axpona show along with the MainzD8 and 2 ceramic power cords. I'm using the built in Dac and it sounds better than the Naim Dac and XP5SX p/s. I don't use the phono stage because I don't have a pottery wheel. Now I am waiting to hear the D2 vs D2.1 before deciding if I'm going to upgrade. The problem with Axpona this year even though they had D1.1's this year they had a full D-TC cable loom and and I know that affects the sound in a great way. So I can't really say how much better the D1.1 is ever after owning the originals. That D-TC loom 'retails' north of 100K not to mention the isolation discs - cable lifters - rack and Sparkz harmonizers.
Now when I first had the D1's and D2's I had the speakers 7 1/2ft apart toed in pointing to my shoulders. When I got longer speaker cables I was able to get them 9' apart. What a difference.
