I really love the sound of mine. I'm using Takatsuki TA-300B, Takatsuki rectifier and a Kenrad 6sn7 NOS.
It's sort of a pain to have to turn up the 2 volume controls, but channel balance is very easy so it not a big deal.
I have not used any speakers so I'm not much help with that.
They do cost a lot, so it's hard for me to really recommend them but if you want the SOTA headphone amp and cost isn't an issue - they are the best that I've heard. The only amp that comes close is the Apex Pinnacle. The WA234 looks great and is built like a tank, definitely not only sounds but also looks like a statement piece.
I haven't done much tube rolling, but as time permits this winter, I'll play around with it.
