One might assume that the simplest audio chain is sonically best, but my online empirical research shows a mixed bag - sometimes the sonics sound better with a preamplifier in the chain. Some surmise the preamp may somehow be conditioning the signal to be more favorable (ohms?) to the amp.
The HoloAudio May DAC would be my choice based on online reviews. Perhaps you can stretch to the Lampizator Baltic 3 DAC at $6.6k - reports that it’s sonics are way above it’s price point - it appears to be a very rare bargain.
