Due to my advancing age, I thought by Goodmans you meant the 1960's Maxamp............. Oh dear.......
Try to find a vintage Rotel 820 series on ebay. The BX varients had been designed more for European tastes and sounded much clearer and more neutral than their gadget laden seventies predecessors - less audible crossover distortion as well....
The Creek 4040 is still cheap enough and later ones very reliable andthe NAD3020/a/b is a stunning old bargain. The biggest bargain of them all for me though (unless them pinko fishies have 'ad 'em all) is the A&R A60. Even early ones are good, tweakable and the only thing that killed it off was its retail price compared to the competition by Rotel and Creek at the time).
Tear down these walls; Cut the ties that held me
Crying out at the top of my voice; Tell me now if you can hear me
