You can easily get into tubes for 1K or less. There are many, many options.
In the used vintage category, a refurbished Scott 299 series integrated amp is a wonderful amp that will give you many years of great sound. I got one for about $600.00 a while back and paired it to a vintage pair of KLH 17 speakers. The combination is heavenly. The Scott has a very good phono preamp built in. You can find them on Audiogon, here at Barter Town and on ebay. Unless you can work on it yourself, you need to make sure the selenium rectifier and the caps have been replaced. Also, you can get some Russian tubes from Jim McShane that can be used in place of the power tubes.
In the used new category, a PrimaLuna Prologue One is a dandy integrated amp with great sound, low maintenance and great build quality. It doesn't have a phono input built in, but you can get one if you want it. I got one of these for about $900.00 used and still use it in my office system.
In the new category, Jolida and Yaquin make good enrty level amps and can be obtained for under 1K. Check with Underwood Wally for Jolida equipment. You can also visit the Pacific Valve website for specials.
If you're willing to spend more than a grand, Cayin makes excellent tube amps. I have an A88-T in my home system that I got used for $1200.00. It is my best amp and hasn't been replaced in over five years. It is designed to sound like a McIntosh 275.
Happy Hunting!
