I agree that the source begins to either show its flaws or shine when the HD800 is in the chain. Im still firm on my opinion that it has little if any warmth at all, and I was using the D18 dac--which is known to be quite dark. I suppose my opinion of the pairing having no warmth is from comparing it directly to the A18 amplifier.
My experience with the Mjolnir and HD800 combo has been quite good using the Oppo BDP105 as my source going all balanced to the amp. I find the combination to be incredibly neutral and transparent. There is plenty of authoritative and accurate bass slam and I find the high end to be troblesome only with inferior recordings. With SACD, high-res files, and even well recorded redbook sources, the highs are crystal clean, but not brittle or fatiguing. I have been very satisfied with the combination. It is extremely revealing, however, of poor source material.
