Deltec DPA DACs - PDM1 and Bigger Bit

Hi again,

Still on my search for bargain vintage DACs that can do a good job :)

Have come across the Deltec DPA PDM1 series 2 and Bigger Bit.

Anyone know anything about them? How they sound, etc? TIA.
I have Pdm 1024 and "Little Bit" series two. I compared their-once- most expensive unit with the least. Little $300 unis is one great DAC. The differences were there but not $9700! I don't think you will be disapointed with Bigger bit.
Thanks for your impressions! Got a Bigger Bit on the way. Should be able to compare vs a Meridian 563 20-bit next week.
