Got one from Todd the Vinyl Junkie too measure the output impedance----Thanks Todd!
Using a 1kHz tone with 0.410 Vrms output into an open circuit
With 32 Ohm lod voltage dropped to 0.167 Vrms for a 46.56 Ohm calculated output Z
With 150 Ohm load voltage dropped to 0.312 Vrms for a calculated 47.12 Ohm output Z
For a technical newbie, what does a high output Z mean in terms if listening experience?
Wow... so it's official then, purrin does NOT have a busted unit.... oh well.
It also means that Purrin has much better hearing than Computer Audiophile's Chris Connaker, Audiostream's Michael Lavorgna, the Tone Audio reviewer, etc. Not bad at all Purrin! I wish there was some way to tag a user as having "good ears".
^^^I find that unlikely. But I do wonder if they were using it as a headphone amp or not. It might be fine our of the line out. Haven't read their reviews...maybe I should.
In the case of audiostream it could have to do with the politics of the stereophile network, which Tyll/IF is also part of.
It would be fairly disingenuous to review a portable dac/amp as a dac only. Defeats the purpose of having such a device if you have to carry another portable amp around.
