New Pre or Integrated for 2nd system, thoughts?

Looking to create a 2nd system inexpensively (max $500, new or used) in vacation home. Speakers are old but functional Thiel 1.2s, late 80s vintage NAD CDP and B&K ST 202. The B&K has 150 watts into 8 ohms but does not double down. The Thiels are a 4 ohm speaker which like high current. Pre has died. Not an absolute requirement but a remote would be nice. So the question is to go with a new Pre or Integrated? Would appreciate suggestions on which way to go and recommended gear. Thanks!
