Looking for preamp which is good at BOTH single-ended AND balanced output


I am looking for a preamp which sounds good at BOTH single-ended or Balanced output. My DAC has both single-ended and Balanced output. I have vintage tube amps which only allow single-ended input. I also have SS amp which only allows balanced input. I use both amps alternatively. Sometime I even use both together for bi-amp setting.

Is there any good used preamp under $3000 recommended? I have opportunity to get BAT VK-30SE or 31SE, I know they are good for balanced output, are they equally good for single-end output?

even use both together for bi-amp setting.


Are you using an active line level crossover when biamping these two amps. The balanced connections will be louder because there is a 6db increase in gain.
I’ve got a BAT VK-3i and a VK-33, both of which have single and balanced outputs. They are terrific, high quality preamps and sound great. I think you should be fine with the VK-30SE or the VK-31SE. You really can’t go wrong with BAT gear.
The over-looked EAR-Yoshino 868L, designed and built by the recently-departed Tim de Paravicini, occasionally available used for around $3,000. The 868 sports two pair each of single-ended and balanced outputs on it’s rear---all independent of each other, the balanced outputs created via Paravicini’s legendary transformers. Each output is capable of driving a 200 ohm load, a brutal task required in pro recording studios, a field in which TdP did a fair amount of design work. Amplification is provided via a pair of 7DJ8 tubes.

EAR-Yoshino is distributed in the U.S.A. by the firm doing the same for two other superior UK companies: Townshend Audio (the unique Rock turntable---currently unavailable, the line of Seismic isolation products, a passive pre-amp, a super-tweeter, and interconnect and speaker cables), and Helius Designs (tonearms). Paravicini chose the Helius Omega tonearm to mate with his Master Disk Turntable.
