Mcpherson, that other thread we were both on seems to have been deleted. Long time, no see. I would imagine an extra investment would make a difference, but only you can decide it it's worth it to you. I own the Doge and really love it, but don't know how much warmth you're looking to impart. I don't find it to be as warm as some other tube preamps I've heard, but that's a matter of taste and could likely be tweaked through tube rolling. I got the upgraded tubes and haven't done any rolling.
It couldn't hurt to audition other linestages before you buy. If you look into tube linestages without phono sections, you should have a lot of options and be able to get into a more established brand at around the same price as the Doge. I've heard good things about the Rogue Metis at just over $1k, but have never heard it. Once you're at $2k, without the need for a phonostage, I believe you're also in CJ and ARC territory. Will you like them better than the Doge? No way to answer that.
It would be great if you could audition them, though, with your own equipment. Buying without an audition is a real crapshoot. I have done it several times in the past year and it has always worked out, but I don't think I will do it again. It doesn't suit my personality type, I guess. On the other hand, if you don't mind the process of buying and selling things on Audiogon, it is a great way to try things out. And you avoid the ding of being the first buyer, who takes the biggest hit when it comes to depreciation. When I go to sell the Doge ( I already know this will happen...too many boxes...desire to simplify) I will take the loss. This would happen with virtually any brand. Look at the Thor's original price. :) If you're buying the Doge new, you'll have 30 days to decide and then pay the 11% restocking fee+shipping if you don't like it. You may like it as much as I did. Feel free to PM me if you have any questions about the Doge. I'll answer whatever I can. Those Focals are beautiful speakers. Hope you're enjoying them.
