Not surprised by your impressions. I own Teac's reference CD player (PD-501HR) and find it really impressive as well, whether as a stand alone player or spdif out transport. Thank you for your detailed, informative and whitty survey.

i've had my ud-301 dac longer than i've had any single piece of kit i've ever had, except for the wadia 121 i had and loved, but i think this is better,
much better , you nailed it,the wadia retailed at over $1200+ when i got it, the teac, i got for $350(warehouse) off amazon.
i see right now, a new black one can be head for $300 ! stunning bargain
i agree wholeheartedly , the teac sound is smooth, a slight touch of warmth, but detailed, and well controlled top to bottom. killer !
