Denafrips Venus 1 vs Venus 2

i would think the dena site will specify the areas of improvement

otherwise a quick email to alvin at vinshine should yield a timely response

I agree with the above post. Please call Alvin at Vinshine Audio. please see link below for contact info:

I think the main differences are (but it's worth checking with Alvin):

Improved temperature controlled crystal oscillator. 
Clock outputs to work with Denafrips Digital-to-Digital converters.
Power supply improvements using higher quality filter caps. 

Earlier this year, I upgraded from a Terminator (first gen version) to a Terminator Plus and added the Gaia DDC. Using the Gaia with an i2s connection to the DAC resulted in a very noticeable improvement. 

Even if you are only looking at the DAC right now, having the ability to add a DDC with synchronized clocks gives you a nice upgrade path for the future. 

but seriously -- they have 4-5 dacs in the line, spaced out carefully by price tier

now they roll out ’improved’ versions... i would suspect the improvement are very very marginal

i wouldn’t hesitate to get a used ’dot 1’ version and save a few bucks if one is available

seems like the western world marketing grist windmill turns on the lights in southern china too!
