Buy around 100 gram few pieces of pink quartz( they are cheap price) and 2 or 3 pieces of banded madagascar agate around 100 and 150 grams, tourmaline is also good but price little higher.. (bid no more than few dollars for that on
ebay be patient dont go over 10 buy with china free shipping offer only) put them on the top of your electrical panel or attach them in front of the breakers that is the one of your audio room.... If you cannot make there because you dont own the house, put them on the socket wall with blutack, or on the surge protector or power station, and if you have some more put them near the location of the transformer of your amplifier, if one stone act not to your liking try another kind, all stones act complementarily used in my system for optimal filtering effects, some clear different frequencies and some act on the soundstage and imaging more etc i cannot go more about that here and now...
Except for the quartz, used also by many known audio companies, acoustic revive for example,because of his very known damping property(
by the way i dont recommend that you buy ANY finished product by ANY company because that are too costly and you can makes the same and way better because you will be using in the end many more species or kind of rough stones, by yourself with more fun taking your time),nobody teach me the details and it takes me almost a year to discover the good species of stones, to try many combinations of stones on the many combinations of spots distributed in all links of the system to the electrical panels to even the headphone in some case Then experiment with the location, the optimal filtering effects depend of many factor in your own gear.... Thanks for your open spirit... You will see that this is less costly than any hyping upgrade gear sell here by the crowds and very satisfying and fun to play and experiment with....
Report here....
Also these stones and crystals are not the only important thing to do....
Damping all links in your system against mechanical negative resonance and vibrations with sorbothane and other materials is very important to.... read that on the sorbothane thread....
remember that not one kind of stones act the same, then with passing time and experiments you will determine the better stones to use, the location, and the complementary effects....I will not go further for the instant...If you have questions it is better that you contact me in private because this is not the thread for that and i dont want to excite closed minds...

Richard51 - I know some here (perhaps 'most' in fact) don't believe your Crystal implementation when it comes to improvements that can be had in a Hi-Fi system. But I am open minded (and hopefully not gullible) - can you start me off by recommending a Crystal - where you can buy them - and where to put it to further improve the DAC-3?
Hey why not give it a go before dismissing it
