For the first time in quite a ages I’ve had a day off work and had a nice three day weekend. I was feeling mildly ill on Sunday and it was very cold so I just spent the whole day in bed, also for the first time in ages, and played Trapt on PS2. I managed to get all the way to the end and some of the last levels are on the verge of being frustratingly difficult but as a whole, I really enjoyed the game; enough so that I’m tempted to play it again sometime (Some of the story is different on a second play through.
I’ve also been upgrading some of my audio gear. I heard a while back that Shure was coming out with a new pair of quality in-ear canalphones and I’ve totally enjoyed my Shure E5c pair so was quite interested. After quite a bit of research on the new E500 model it appeared that they would be my kind of thing so I pre-ordered a pair. About a long wait, about week before the shipping date I was notified by the supplier that Shure did not want them sold outside the US. It seemed every store I looked had also been given the same instructions from Shure. I was busy planning some way to get around this problem a few days later when I got a second email from the supplier telling me that Shure had authorised them to go ahead with my order! I guess that’s what comes of being a returning customer pre-ordering some expensive gear (I ordered my Shure E5c pair from the same place).
I’m currently waiting for these things to arrive although I’m not looking forward to the GST bill from customs.
When I was doing all my research on the new earphones, I was finding many people saying what a difference a headphone amplifier made. I’d always intended to pick up one of these things but just never got around to it. I did expect there to be some difference between the amp that typically comes built into something like an iPod and a dedicated quality headphone amp but I did wonder if I’d really notice that much difference. I don’t mind spending some extra money if something sounds noticeably better but I’m very resistant to spending extra if I can’t pick it. All the comments I read though suggested the difference was actually quite significant.
I ended up deciding to jump in and ordered a Xin SuperMacro IV headphone amplifier which ended up on backorder due to heavy demand. In the meantime I kept reading and thought I might try to pick up a cheap valve-based (or tube-based for those Americans) headphone amp to play around with to compare and contrast to the op-amp based SuperMacro. I ended up finding a new Xiang Sheng 708b on ebay and managed to win the auction. This is a Class-A Chinese preamp with a quality headphone output. It came with a series of Chinese valves but I had already verified that they were compatible with some commonly available valves. This arrived about a week and a half ago and I carefully started burning it in. The difference was huge to put it bluntly (I’m using line out too B.T.W, not the iPod’s headphone jack like some). A few days ago I swapped the pair of 6N11 output valves for a compatible matched and balanced pair of JJ E88CC valves which are still in production and quite cheap. After some more burn in time, this too made some noticeable improvements to the sound. I’d like to try some quality “New Old Stock” (NOS) valves some time but they’re a bit pricey to add on top of the price of the headphones and the two amps at the current point in time.

So, anyway, the Xin SuperMacro amp arrived the other day. It’s a very cool and flexible piece of kit, smaller than a credit card in length x width and less than 2cm tall. It takes 8 AAA batteries and manages the charging. I gave it a number of hours to burn in and then started listening. On my first listen I was a little disappointed, the Xiang Sheng 708b sounded noticeably better which just goes to show that more expensive/newer technology definitely doesn’t always mean better. On further listening, I felt my initial impression was a bit harsh, the SuperMacro totally blows away the amp built into the iPod. It’s also much smaller and portable than the Xiang Sheng.

I want to write more about how these two amps actually sound and how exactly they are better than the default amp on a typical portable device such as an iPod, PSP or Discman but this post is already too big.
Some other time…
