As I stated in your other thread, I will gladly endorse the Raptor. And as was stated earlier in this thread, the 800 and the Raptor are fantastic together. It really just depends on the sound that you are looking to get.
As far as quality, you cannot find two better people to do business with than Ray or Jack. Both build outstanding, high quality, glorious sounding products, and both are super gentlemen who will do all they can to make sure you get great sound.
I know it's tough to hear, but you really can't go wrong. I'm sure you will be floored with either purchase. Both will sound great with all types of music that you throw at the. Do not hesitate to call each and see if they will let you demo one. Ray was kind enough to send me a Raptor to trial, and Jack sent me a WA6, I just had to put down a deposit on it.
So I spent two weeks with having them both, and than...kept both b/c I really enjoyed the unique qualities each had to offer. Over the long haul, I just couldn't justify keeping two tube amps. I found I listened to the Raptor more over the long haul, so that is what I kept. No regrets in any way, and I've never felt there was anything missing that would make me want to upgrade. Another bonus for me is the Raptor has a very small footprint and fits nicely with all of my other gear in the limited amount of space I have allotted for it. One of these days I'll post some pictures.
Again, my audition came with a stock WA6 and not the SE vs. the Raptor. As I said above, you really can't go wrong either way. It can't hurt to ask and see if you can demo them, that way you can let your own ears make the decision. Good luck!
