LM3875 is easiest choice, but it means i'll have to use dac's bal>se stage which consist of opamp followed by a buffer (lme49600) and their neg.feedbacks which doesn't make it as short and straight as balanced outputs to say bridged LM4780 which are also coupling caps free (If common-mode DC is not a problem, can null differential DC). Or maybe i can use paired LM3875 in bridged configuration?

My speakers are 95db and 6 ohm minimum so should be easy load for both?
I'd appreciate opinions/suggestions
Hi Alexander
You can use Buff dac with output stage from lampizator then to chip amp, I'll do it to connect it directly to my LM3886. This may be a much better output and... no opamp!

Lampizator - AMBER TUBE KIT
FWIW, I ran a DAC (1541a) with Lampizator output hardwired to Peter's LM3886 via (lightspeed attenuator) happily for 5 years. First class sound. 2 components you can't do without are Peter's delux kit, and Lampizator output on your favorite DAC. If I recall the Buffalo is a voltage out DAC in which case you get to use the fabulous 6n6p tube. Otherwise if current, 6np2 is the winner.

Default Terrific sound

Hi Wlowes,
That's the way to go, I agree.
No matter the dac, nos, sabre, (the best as possible), I lampizate it to the LM amp.
And we can forget single ended versus balanced, (in this case....).
I'm glad to know you have the output stage from Lpztr. It means that may be I'm not crazy.
