Just started listening to headphones (Creative Aurvana Live 2) after having lost a pair (Grados) that I ignored and hardly ever listened to. Listening to headphones is making me hear what is really possible when the resolution is very high. My system cannot achieve that level of resolution, but it's decent. Been into this for 13 years. I've been through many amps, speakers, and sources over the years: Bryston 14BSST, McCormack DNA 500 (probably shouldn't have sold), Cary MB500's briefly, Harman Kardon HK990,NAD M2, Mcintosh MA6900, Blue Circle BMPH, Wyred ST 1000, Cary CA306, Classe CA 200 and currently own a Yamaha A S2000. Many speakers: Def Tech 7002 and 7000 (heard them in store, liked them but should never have bought)these were my first speakers, Reimer Wind Rivers (probably should never have sold),Talon Raven C,(definitely should never have sold), Def Tech Mythos ST, Walsh 5000 prototypes, Mirage OMD28, and Klispch RF 7II. Still have the Mirage and Klipsch. The problem was at the time I owned some of these speakers, I did not hear them first. Then once owning the speakers it's important to keep trying them with as many amps as necessary. But, after not getting the sound I thought was possible with a couple different amps, I would sell. Even trying two amps with speakers isn't enough. It's all about the choices you make at the time you make them. I'm sure I could put together one heck of a system if I could piece together one system from all the gear I've owned. I've learned you must put the speakers with the sound you like (or love) with a complimentary (matching) amplifier, and then build the rest of your system around that pairing. First you must hear the speakers and make sure you like the sound. I almost always bought used without hearing many of the speakers first and then struggled to find amps for them, so my path was the wrong one. For me though, it has always been about loving music and not about loving gear, and definitely not loving spending money on gear. By this late in the game, I have spent lots of money and am too invested to stop trying and accept less than a satisfying system. I think I have achieved that now with the amp I own, but the cost has been much more than it needed to be. It's been frustrating. The best amp-speaker pairing I've had so far has turned out to be an amp and speakers that have an ok reputation and cost quite a bit less than the others. So another thing I've learned is that cost does not always correlate with performance.
