Helllo, fellows TBers, Again I am facing the moment to make the choose between the two amps. I was offer a Eden WT400 for 500 CAN, but the seller back out for some wierd reason, he just decide not to sell it after he took my money. Fortunatly for me, he did give me back my money, but left me with no amp. So I come to a amp search in Ontario, and found a used GK 1001RB for sale 680 CAN on the Internet. It's in Ottawa, so its gonna be hard for me try it out. Or I have the other option, the Yorkville XS400, which seems to be very highly-regarded on TB and all the review site, and it has the tube preamp i am looking for, so i figured that would be a good choice, too. The brand new one that I can get mine hands on would be 790 CAN? What should I do? which one of them sounds like a better deal?
