personal experiences with quaility preamps...

I would get 2.5K nice used power amp and FT-Audio LW1 (passive controller). FT is a raved here and there $500 passive pre, and it it really a bang for a buck. www.ftaudio.com. If interested, email Paul there. Ken

i can't help but recommend rogue audio tubed gear, it's what i own and i can say i've been very satisfied these last 7 months. clearly there is stiff competition in the market and better gear, but i think you have to spend considerably more.
my rogue 99 magnum was had for about $1900 and a very well cared for rogue 88 power amp (non magnum) was bought used on audiogon for about $900. sounds like this fits in your budget.
you can always buy non magnum versions and have them magged at the factory. check out www.rogueaudio.com for more info, or better yet call mark o'brien. he listens, does not push, and provides great customer support.
btw i think i've recently seen a 99 preamp for about $1300 on this site. you may also consider the m120 monoblocks since you seem to have the budget.
compare against whatever else you can if possible.
hope this helps

For $2K, you could have a BAT VK3i tube pre and a McCormack DNA 0.5 dlx ss amp(125 wpc) or BAT/DNA1 (185 wpc) for $2.75K. Very nice combo. Either would leave you with some $ for used cables. A lot depends on what kind of music you listen to and what your present/future plans are for speakers (in terms of the load, current demands, etc.)

I had an anthem Pre 2L for a while. It does a great job with most everything I threw at it. You can pick up a used one for about 650. As far as amps go, anthem makes some nice ones that compliment the pre. Check out their website. Also, I've had pretty good luck with the more expensive Parasound amps.

I would get a McIntosh amp and pre. I have owned 5 separate systems and then I got a Mcintosh setup and I find it is the best in looks and sound. I am now a Mc man. I tried my C712 pre with amps from other makers and it did not sound as good as with the 3 Mc amps I have used so I would buy them as a pair. There are 50 years worth of used ones so a good deal is not too hard to find (except on recent ones). Arthur
