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

I had the Octave V110  before getting the Aavik U300. The Octave really held it's own until pushed to the max. Mids and highs would get louder but the lows stayed the same. BTW what tubes are you using in the Carver? I hated the TS KT120's but never tried the KT150's. I used the Ei KT90 type II with great success (except the lows petering out at max spl's). I've always loved Burmester with Raidho. Naim is very good too. Sim Audio would be pretty good IMO. One thing I found over the years is an amp upgrade has more of an impact when the speakers are better quality. That said the Aavik has a hair more control of the music. Not earth shattering but a bit better.

So I hear you're getting the D2.1 upgrade. I haven't decided yet. Tyler is going to let me break in his D2.1's in my home when they arrive. I have a gut feeling he won't get them back after hearing the D1.1's at Axpona. I did own the D1's for about a year before upgrading to the D2. If you didn't get the D2.1's back yet I personally would wait. I will admit I miss the Octave but mostly only in the winter months. I rarely play that loud where the lows are petering out. The .1 upgrade will have a louder/faster sound by itself.

Have you tried any Ansuz products specifically the Mainz D8 and power cords? To me they don't change the tonality at all but add a more holographic sound stage. Speaker cables and interconnects do the same.

Jeff Rowland - How could I have forgotten that one. Duh - A lot like the Aavik. Are you just tired of tubes - the heat and maintenance? The GL reissue is a OK tube with Raidho IMO (I still have them and many others). Original Gold Lions/GEC/Marconi  are a lot better with the D2's along with Ei KT90's.  EAT KT88 Diamonds are also very good but extra pricey and were not too reliable in the Octave. SED 6550's aren't all that bad either. SED KT88's are a bit warmer and IMO too warm for Raidho D series.

Lars K from Raidho had JR for his amp(s) before the Aavik was released. Raidho also used a lot of Rowland amps in their shows (again pre Aavik). Other Raidho owners from AS who had Pass Labs thought they slow sounding too and replaced them. Pass makes a great amp but not a real good match for the Ho's. Tyler will be getting the Aavik pre/pro which is class A. It will be interesting to hear the difference between the class A and D Aavik.

@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. 

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. 

Honestly the Octave has everything the Aavik has to offer up to around 85-90db. But for the extremely rare times I listen over 90db the Octave just didn't cut it. Also I was able to eliminate 4 boxes (with cables) and replace it with one. Oh and the heat from the tubes was great in the winter months but made my A/C run a lot harder in the summer.

BTW are you in the Chicago area?

Here is an interesting review of Raidho/Ansuz/Aavik. It’s a long read but pretty much explains why I have what I have.

The new Aavik P-300 C-300 should be shipping soon. Looks like class A

@dracule1
I can't disagree with you regarding cables for the most part but I will be the first to say cables should be the last thing you do once your system is finalized. Cables can squeeze the last bit of 'best' sound quality out of your system. That said cables can be very system dependent which is why I mentioned once your system is finalized. Honestly with the right set of cables they can bring your system up an entire level.

No bad. Although I didn't hear 2.1's with the 440 I did hear it with the XT3's. Then we dropped in the Aavik U300 and the U300 had much better control of the music. That said we did use the U300's internal dac when we switched over.
