are older Naim integrated amps considered high current?

searching for a used $1.5k-ish high current integrated

I see Regas in that price  range also

any other recommendations would be appreciated also

high or low current are words, descriptives that are held in the eye of the beholder

that said, naims are considered by the knowledgeable owner base over time to be pretty stout in delivering current into lower impedance, tough loads beyond what their traditionally fairly modest and conservative power ratings would superficially indicate

What are you trying to drive, how big of a room and how loud do you want it?  Most speakers don't need alot of power to make loud noises, typically they only draw a few watts in most usage, but that really depends upon those 3 questions. The NAIM XS is very impressive for its size and weight but there may be better options in that price range depending upon your needs. Personally I'd look for a Willsenton R8. 

while i agree that it would be helpful for us to know what your speaker choice and room size are... in order to help you gauge whether a naim xs/xs2 integrated might make sense... i do not agree that a willsenton r8 tube amp should be considered as an alternative

those two are very different amps with very different capabilities and sound -- if you are worried about ample current delivery by a solid state amp, the last alternative you should consider is a classic design transformer coupled tube amplifier
