Quick impressions from my side, using Utopia 2022 and
mostly Feliks Audio Elise with upgraded tubes. I don't have Hypsos with me at the moment (but I did listen to it with before with previous Wandla). I have Oor as well and I did test it with new enchantments.
GoldenSound improvements are subtle but noticeable, actually a lot more than changing a HQ filter.
These changes are not overdone and if you already like how Wandla sounds, then this will be a nice addition for you.
Impact+ is most noticeable right away because its basically and EQ change. I thought there is more to this filter than this but sadly it does not seem like it. This means with some headphones (like Utopia) lower tones will get boomy and way too punchy, but in some cases this change might be a nice addition.
Spatial Enhacement depends A LOT on the song used. You can hear a better instrument separation in most tracks, in others perceived soundstage (or room) gets bigger. Most of the time effect is nice to hear, and yes songs feel compressed after you turn this effect off aster using it for some time, but in some examples this effect can be a little too much as well, like when there is an echo or reverb used in track then it will get much more noticeable. Still, for me, this is by far the best new feature added to a Wandla. The fact that you actually want to use this feature says a lot about it compared to other similar implementations. Great work team @ Ferrum and
@GoldenSound !
Tube Mode is very subtle and alter sound only a little bit. This does not emulate a real tube amp at all, and I think this was a wise design choice as change is very delicate, little bit analog-like without losing any details or so on.
Overall, even if these changes are subtle and asking/update price is a bit much, I would still recommend upgrading to GSE. You will get an improvement in sound, and better, you can support amazing work at Ferrum and from the GoldenSound. We need more initiatives like this to keep this hobby evolving. Once again, great job everyone!
