Sugden A21 Class A & TAD-150 tube pre-amp

I am looking to purchase a Sugden A 21 class A power amp (25 watts into 8 ohms). I have seen many great reviews of the Tube Audio Design 150 tube pre-amp. Would a 25 watt Class A Sugden be a good match for a TAD 150 tube pre-amp? I am not sure if the class a/tube combination would be a good one. Any advice, especially from TAD or Sugden owners would be greatly appreciated.

the sugden integrated or pre/power combo would be an alternative. sugden actually counts on synergy.
