Raidho speaker owners, what solid state amplifier do you use?

I have a Chord SPM600 (and Chord pre) with my D3s and it's a terrific match IMHO. The Chord drives the D3s with ease and clarity. However, I desperately need to upgrade the power and cabling, which is next on the "hit list". I hear good things about Mainz D so I might go for that. However I am skeptical about paying a large sum for a wall power cable as I have just installed a dedicated power circuit - but I'm open. While I have heard (and loved) the Aavik U300, my Chord should probably last for some time, I hope.

@chronoglidesky - The Ansuz MainzD8 is quite amazing. I have a Ceramic pc going from the Mainz to my Aavik U300. I just recently upgraded the Ceramic from the wall to the Mainz to the D-TC pc. Quite amazing. Like I mentioned above the Ansuz cables doesn't change the tonality but adds a more holographic sound stage. But I will admit the D-TC opens up the sound a lot more almost like turning up the volume with greater clarity. But it does come with a pretty hefty price. Honestly if you have a chance to listen to the Ansuz products do it. Lars and Mike recommend the best pc you can afford to go from the wall to the MainzD8. I can hear why. Secondary power cords-interconnects and speaker cables will make a difference but not as dramatic. 

Thanks xti16. I'm new to the Raidho family[*] and interested to read any opinions on how to extract the most from these beauties. MainzD8 would be a good step.
I heard the Aavik (at Axpona) and was very impressed indeed, especially when compared to the other "big box" amps that were littered throughout the show (often 4x larger in size). I look forward to seeing other members' comments on this amp, especially how the phono stage fares when compared to, say, a Sutherland or other such fine units.

[*] FYI: My mind was set on Wilson Alexia's - but I changed it after Axpona. The D1s, while smaller, "hit the spot" and it was obvious that the bigger D-series would just deliver - big time.

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. 

Thanks for the comment. It seems to be an interesting "leap" from tubes to Aavik. Would you say the Aavik is comparable to tubes (musicality) but with the response and timing of SS?
Yes, the cabling in Raidho's Axpona room was impressive - I would love to hear the same demos over again, but with lesser cabling.
