Hi,
Pani I`ve own the Yamamoto DAC for about 18 months(see my system) it is an excellent sounding DAC.It is very natural with quite an organic presentaion. The dynamics and tone/timbre are honest with a full bodied sound,yet with exceptional resolution and nuance. So far I`ve not heard any other DAC that I`d exchange it for.
However It seems the Metrum Acoustic Octave DAC may be superior. You should read it`s review in the current 6 moons.com. Also read the review of the Totaldac and then read S.Ebaen`s second opinion review.
Please note what the Metrum was compared to for context.I purchased the Yamamoto based on Srajan`s review(he was absolutely spot on). He`s more impressed by the less expensive Metrum. I`ve ordered one and am waiting patiently. This DAC is NOS(no digital filtering) but with R/2R configuration using ultra high speed industrial chips, not the common delta sigma types. It`s said to be sumpremely transparent, organic-analogue like, but with excellent resolution and ease.Much more resolved than most current NOS DACs.
Best Regards,
