Watt Puppy 7 needs new or used Amp and Pre-amp


I'm building my system on a pair of Watt Puppy 7 speakers. Currently I have my vintage Marantz 250 amp with an SAE Mark 1B Pre-amp/equalizer.
I think the preamp needs to be replaced first. I need some advice on putting together a system on a tight budget. Thanks for helpful advice!

Used Musical Fidelity integrated amps would have plenty of power and sound very good. The NuVista M3 , which I use, or the later similar models are excellent amps and are very reasonably priced for their performance. I am an audio dealer but I don't sell Musical Fidelity.
I think they would sound nice with an all tube system.

How much do you want to spend?
You can do a vintage Luxman system for $ 3,000.00 range or
audio research or Conrad Johnson from about $ 5,000.00 and up
Do you have a large room?
Do you listen to Led Zepplin really loud?
FWIW, the Watt/Puppy system is designed for tubes. They are easy to drive- our local dealer demoed them with our 60 watt for years. Wilson's national sales manager has used tubes for at least the last ten years...
Tube pre - ARC LS5 MK II or III or LS26 - Amp - NuForce 9SE V2 or Classe CA-2100
