People may not agree, but I found the Conrad Johnson Solid State line of amplifiers to be very warm and actually quite "tubey" in sound.
Now, they are not the best amps out there - but they are very warm, musical, & have the signiture CJ sound. They can be found for under $2k. I Demo'd MAC's and lot's of others - IMO the CJ is one of the warmest amps I have heard. I ultimatley choose to go with VAC - but if you want the tube sound without the bottles - CJ is as close as I have heard.
