sooo ...... here are my initial impressions after hooking up Modi / Vali to my PC and listening through HD598 .... (by the way, will have a chance to test that combo with HD600 possibly tonight).
It's weird .... mostly good weird :-)
So for anyone who heard HD598, you know that these are considered warm and somewhat bright (not as bright as Grados, but still on a bright side, maybe for lack of deep forward bass).
What I noticed when I hooked up the modo/vali combo.
Right off the bat, sound quality did NOT double or holly molly what a crazy difference ... let's not kid ourselves. The biggest return on investment is buying a headphone ... then all upgrades are somewhat marginal.
so ... I am still surprised how sound was modified due to the combo. Not to skew my result, I really tried to keep sound volume identical. I noticed that HD598 became a bit brighter and thus ... sounds like it now has more detail. It's strange, I always felt like HD598 were kinda on a bright side and yet after listening to modo/vali, going back to no amping HD598 started sounding a bit dull and muddied. Can that be???
I also noticed that cymbals, guitars, etc became more forward. Not sure if I love how female vocals changed. I am almost ready to say that modi/vali is not a natural dac/amp .... they do brighten up the sound. Or maybe it is a natural sound?
The crazy thing is, going back to not using this dac and amp, is like reverting to something not as good, so does that mean I am hooked now? :-)
I have a feeling that HD600 will be a much better match for modi/vali. Reason is ... when I listened to HD600 using just my PC sound card, they sounded kinda dull. Also not loud enough. When compared to HD598, I felt like HD598 shined and sounded better than HD600. Now with the DAC and AMP, I feel that modi/vali is exactly the medicine that HD600 needed.
anyway, I am eagerly awaiting this evening to hear my friend's HD600 with Modi/Vali.
I feel like this testing may never stop. Now I am curious to hear the famous HiFiMan HE-500
Is what I am saying making any sense to you guys?
