I have a second chance at one that appears to be mint ...with demo-ability; in pix of a nice living room; so it's set up and 'everything works'.
But is thirty-five years too aged ? I scored one from my local thrift for $45 bucks? a decade ago... But of course it lost a channel and I 'returned' it.
I live in an apartment and only get to listen at 'energetic conversation' levels -and let's face it; this is about where most listening is done.
hah! I should quote my $50 PSB Statement Cables ( talk about a python ). Topping e30 Dac... and my Yaquin vk2100 ( it has toobs ! )
I am lucky to be listening through a pair of Celestion 5000's. They are better than the 3000's because they are walnut veneer; but I digress... They are rare and have an electrostatic strip a couple of feet long on a 45 degree corner... and very often surprise with excellent imitations of Frank Zappa's musical instruments -but perhaps not his bands; due to that Levels thing...
I say lucky because if I equalize the levels between them and my Stax 300's... there is an equalized level of listening enjoyment...
Sorry for this rambling intro ... but I need some old-timer's advice and here in Whistler it's a long way to a friendly technician...
Perhaps the saving grace is that the 6250 would be under such little stress.
ps: The real problem with audio-philly is that Stereo is Easy compared to finding new music that keeps you up late on a ski-night.
like WakaWazoo or Erie did; if ya' know what i mean...
