I really appreciate all the input. So here's where I am right now...
I replaced the tube in the GP12 and so far it's behaving itself, so I don't have to replace it immediately.
I'd like to pick up an Alembic SF-2 and maybe a F-2B when they present themselves at very reasonable prices. However, I don't think I will be able to use these as my main performance preamp. They would be for experimenting and recording.
I've pretty much narrowed it down to two that have the flexibility and features that I need: the Eden Navigator WP-100 and the SWR Marcus Miller M2. Similar features, similar price. Proven, reliable, quality design vs fresh new design taking advantage of the latest technology.
I'm hoping to find some place where I can play them back to back. I suspect that they each have a signature sound instead of being completely transparent. I don't think I want to just jump in and buy one sight unseen like I did the GP12! If anyone has played both, I'd like to hear your impressions.
Thanks,
Loch
