Thoughts on Audio Research D70

I recently saw a very well priced D70. If I remember back in 80's these were highly thought of. Having no chance to hear, what do they compare with today or do they?

No more oscillations. All diff amp balances measure AOK. Gain is too high for my liking so in a sense it's indeed not quiet enough. Maybe a triode mod will give me the extra benefit of lowering the gain. The sonic signature is not lightweight and refined enough, lots of power though. I guess its what full pentode/tetrode mode is all about.
