I have the same experience with CJ SS gear, and recently commissioned Jim Nicholls to make a tube amplifier with enough juice to push my Dali 400's. The amp weighs 80 lbs., has 8 output tubes, and can handle el34/6ca7 as well as KT88/6550's. I currently have Electro-Harmonix 6ca7's doing the job, and the amp sounds fantastic. The grain is totally gone, the soundstaging is superior, almost 3D holographic, and the mid-range is to die for. Also, bass is strong and tight. What's not to like? Jim modestly rates the amp at 80 to 90 watts per channel, but his teacher, Lance Cochrane, thinks the output is well over 100 watts per channel. in any event, with the increased sensitivity of this particular amp, I can play music at loud levels and still not strain my CJ PV-15 pre-amp. The amp is also auto-bias, plug and play. It only set me back $1500, and the amp is clearly competitive with more well-known brands costing 3 or 4 times as much. I would suggest getting in touch with Jim and asking him to build you an amp. His webpage is called "Glass with Class", and there is a review of his amps on Dick Olsher's review page. Just google "Jim Nicholls tube amps".
