best tube preamp under a 1000 for B&K 200 sonatas?
I have a pair of the B&K mono block sonatas...currently using a B&k ss pre....I would like to step into a tube pre but don't want to spend more than a grand. Definitely buying used. Running paradigms studio 60's. All suggestions welcome. Thanks
You want the output impedance of a pre to be at least 10x less than the input umpedance of your amp, across the audible frequency band. To be safe, and since we often don't have measurements available across the spectrum, 20x is often recommended.
