Comparing AmpsThe SR-71 is my first amp. I bought it for my iPod. So when I upgraded sources, from iPod mini to Denon DM31S, to Rega Planet 2000, to Meridian G08, I had the pleasure of using it as a "home amp." At the iPod level, the superiority of the SR-71 over the Rega Ear is evident in terms of detail and soundstage, but not by much. With the Rega Planet 2000, the gap widens even more. With the Meridian G08, the SR-71 outclasses the Rega Ear. To date, the SR-71 easily competes with my HR-2 in terms of sound quality. It is no wonder that the SR-71 is my amp of choice when auditioning high-end sources at local audio shops.
What I am saying is, IMHO, if you have a low-fi source, such as in portable applications, most of these amplifiers will probably sound close enough that I would get the cheapest, best build, amp. You really don't get your money's worth until you upgrade the source. Ray and Dr. Xin will probably kill me for this, but for portable use, I would spend my money on a UE10 pro or Sensaphonics instead! LOL!
cheechoz, congrats on the purchase. You will not be disappointed.
