IMO tubes will sound good with Raidhos unless you push them. I had an Octave V110 when I had the D1's and later the D2's. The biggest drawback was when you pushed them the lows just fell apart.
That said I found the Ei KT90's for output tubes were great with Raidho's where as original TS 6550 solid black or grey plates sounded mushy. So depending which tubes you run will make a big difference.
Since then I have upgraded to the Aavik U300 and couldn't be happier.
