jojo_b2 0 Report post Posted April 14, 2009 hi jack, I haven't really seen a usable portable Preamp setup. But my guess is use the most neutral and has the widest dynamic range as the preamp. As always if the sound is already cut off from the 1st amp then the second amp would even sound worse or will not be able to reproduce the whole range as you cannot return anything that has been cut off already. To note, this is just my idea and is not backed by actual facts. Btw, why use a portable preamp? Share this post Link to post Share on other sites

heady 0 Report post Posted April 14, 2009 Hi To use your mini3 as preamp, connect source to mini3, then from output of mini3 to power amp. Same for the RA1. So if your source uses RCA then you need two RCA to mini-phono jack cables. Hope this is good advice. If not, then others will surely jump in and correct me.

wwenze 0 Report post Posted April 14, 2009 A headphone amp is a preamp, or vice-versa. Sound-wise, comparing the cheapest versions of RA1 and mini3 I know of, the mini3 undoubtly wins. But if choosing between the two for home use, I'd take whichever draws more power, is comfortable with a voltage higher than 9V, and bigger and more moddable. That would usually mean RA1. ^^ Share this post Link to post Share on other sites
heady 0 Report post Posted April 15, 2009 then all parts can get in sg rite? I have not checked but I think so since the designer(s) chose commonly available parts. My Pimeta had commonly available parts, except the BUF chip which is now almost impossible to find. Regards Share this post Link to post Share on other sites
Guest jacj6049 Report post Posted April 15, 2009 hi chief!!then i think must but diy kit,since no other option for the buf chip...... Share this post Link to post Share on other sites
