Acoustic Revive RR-777 Schumann Resonance Generator
Tuyen:
Interesting device. I heard the previous model RR-77 on a system recently and I could hear improvements in terms of 'ease' and better 'flow' in the music. Soundstage and imaging becomes just that bit more palpable. Was very small music room.
In my opinion, worthwhile for audiophiles who already have the important stuff 'sorted' (ie. speakers, sources, amps, cables) in their system and enjoy critically listening to music on their system. What I mean is that it won't change a excellent sounding system to 'magical' status, but it did give a few % improvements to my ears, which lets face it, for us anal audiophiles, often means a lot! Either way, I reckon some here may be pleasantly surprised! ;D

Treblid = Myrantz (i.e. troublemaker trying to get himself banned on other forums, couldn't figure out how to name change here)..
Not sure if I can hear the difference myself TBH (it's not very obvious to me at all, I only kept it and use it coz my dad gave me this to get the 777 for himself).
If anything I feel it sorta takes the "edge" slightly off my "edgy" system? And I didn't hear that per se, I actually felt it instead (and this is not 100% reliable)... Does it kind of describe what you're hearing?
According to my dad the 777 is more noticeable/effective...

Hi TJ,
Indeed it is the 'feeling' I get. Not actual tonal change I don't believe.
Wouldn't call your system edgy though. Quite nice. Images impressively.
Might look at one of these units after I get the rest of my system sorted. ;D

So it's not just me.. Every one I tried this with can't hear it, they just sorta feel it (and some like it, some not - I'm still on the fence myself TBH).. It's really weird and I have no idea if it's placebo or not, but personally I don't mind if it's really placebo :p

Thanks :D. Still room for improvement, e.g. I2S, but as you can guess I'm honestly scared to do it :(..

From what I was told they are actually very hard to buy/source. And honestly very expensive for what it is... There's a DIY option, maybe you want to try that? I couldn't find the link+instructions but I read it before.
This device is a straight plug in replacement technique for the "5c audio tweak" which is very common in Singapore... One reason why folks in Singapore snap them up I guess. If you are interested and ready I'd check with my dad and see if he can get a good price...
Tuyen:
I can help you with setting up the I2S connection when you are ready. Bit of hassle switching between I2S and back to SPDIF for your 2 sources though.
Re the RR-777, quite easily available from an ebay search.

Looking at around $450AU with free postage from Japan. Not really that bad IMO!
