Although my WiiM Pro was replaced (by a NEO stream) a few weeks ago I got a Plus for pure curiosity and love for the WiiM idea of a cheap but excellent streamer. And did a short but intense testing with my at hand items.
Fix points: E-280, B&W floorstanders, Dynaudio bookshelves, Sennheiser headphones.
For me only the DAC was the theme, no other features like connections. This order was the result, from bottom to top. (Once more I was confirmed where to place a DACs impact. Improve other things first.)
Did not check the Plus with external DACs because I think the internal DAC from the Plus would be the reason for buying. If one has a bunch of DACs he could easily stay with the "old" Pro. Again, if no other feature from the Plus is wanted.
- Pro with the internal DAC
- Pro with SMSL C100
- Pro Plus with internal DAC
- Pro with Cambridge M200
- Pro with DAC option from the integrated amp.
Should be easy to explain
, because very often (sure not always) the chance to get a better result out of a higher invest is likely. The "audiophile" gibberish is not mine, the higher priced options sounded more correct and adult. Of course it was not a blind test! Did every single connection myself.
But the "differences" with the more expensive DACs are
in such a tiny range where not a single one for me would justify the price differences! As always up to one's ears, requirements and budget. Air becomes thin when chasing a few percents more.
The internal from the Pro was the only one I identified every time immediately in the different speaker/headphones combinations. As a few of you might know in between I do not give much for measuring. I only trust my ears and the developers of companies I know for years and most of the times did not disappoint me. A statement like "the DAC of the Plus plays in the 500 € class" for me is at least a little bit adventurous.
So for the girls or guys with external DACs and lovers of displayed resolutions I would recommend the "old" Pro. For those who start from scratch it is of course the Plus. Both items are excellent choices and do not need vindication. But if it comes to a clash with many of the significantly more expensive competition they will reach limitations. If a high-end really exists the WiiMs are beaten with at least 2 and a half lengths. (Not too bad in horse racing.)
One more final thought: WiiM's software built on a very common basis is in my eyes the best one can get if he or she uses the WHA. Trying to bring it in a popular relation: The Pro with the external Cambridge DAC outpaced my former Nodes, X and i, easily.
Buy what you like and what is within your budget. You'll make no mistake, every WiiM based option is a good one. But the better was the enemy of the good.
