Audiophile-quality micro system

One of the things I find I enjoy more and more as I get older is music. I never listened that much when I was younger, but now I find it’s a great escape. I discovered the bliss of in-ear monitors back in ‘99 when I was traveling a LOT for work, and was using music to deal with the occasional bout of homesickness. My Etymotic ER4-S ‘phones were awesome even if they required an amplifier to get the best sound. It was ok - with a Creative Labs Jukebox, my HeadRoom amp and the Ety’s I was a happy camper.

Later on I got an iPod and later still I moved up to the Sure SE530 phones and no longer needed the amp. The sound & fit are stellar but with small children around the house wearing headphones that block a lot of sound isn’t a very good idea. A frustrated “help me!” call or crying child going unheard is not a good thing. Other than for running, headphones that don’t block sound just don’t make sense to me – if I’m going to hear background noise why not use speakers?

So I was trying to figure out how to put together a small, inexpensive, but nice sounding speaker system for the office and/or shop. I’ve got some old stereo equipment, but it’s a gigantic JVC multimedia receiver – about 18” deep. Not easy to find a home for. I also didn’t need the gazillion watts the old stereo was capable of. Heck, I probably wouldn’t need more than 5.

I thought about getting one of the iPod dock-plus-speakers appliances that a lot of folks are selling, but I don’t need portability and I wanted better sound quality and speaker placement.

After some thought and some reading I figured out that all I really needed was a dock for my iPod, a small amp, and some speakers. I have a set of old JBL 2500 book shelf speakers, and while not great they work for now. The dock was a small purchase at the Apple store. That left the amp.

I looked around a bit and after finding the Sonic Impact t-amp was getting rave reviews from audiophiles I got very interested – the thing is only $30 after all. Turns out that Sonic Impact developed a very cheap amp using a chip made originally for products like big-screen TVs. It is a special kind of amplifier circuit that’s very efficient and produces very little heat. The result is a small, inexpensive amp that has very good audio quality if not a lot of power – something like 10 watts per channel max, with about 6 being the limit for really good sound quality.

Unfortunately Sonic Impact realized the demand and improved the amp and raised the price. Others joined the fray with similar but better designs and the “Class T” audio amplifier market was born. There’s several models out there, and a few companies that offer kits. I think I will ultimately build on of the 41hz kits, but in the mean time I decided on the Trends Audio TA-10.1, which I bought from AudioMagus.com. The Trends is about twice the price of the latest version of the Sonic Impact amp, but it gets better reviews and the build quality (it’s in a metal case with high-quality connectors) was much better.

It’s pretty tiny and has only an LED and a knob on the front. It’s just a simple amp with 1 input and outputs for pair of speakers. Perfect.

So I have an iPod sitting in the dock, the dock connected to the amp which has its volume turned to max. I use the remote for the iPod to change volume, advance tracks, etc. The remote is small and simple and easy to replace if needed.

The sound is excellent at low volume and still pretty good with everything turned up. Something mentioned in every review of the amp was that speakers less efficient than 90db@1 watt would be disappointing and the JBLs are at ~86 so I will probably be replacing them soon. Still, for a system that takes up about as much space as a small alarm clock, and holds about 300 CD’s worth of music encoded in a lossless format, it’s pretty remarkable. If I need to move it to the patio or a different room it’s pretty portable.


Living with the iPhone iDrop

Susan got an iPhone first. She loves it more than any gadget she’s ever had. I have to admit I was jealous - really, I am the gadget master in the family and it didn’t seem right that she’d have a new gadget than I.

But I liked my Blackberry. It did almost everything I wanted, and it was a darn good phone to boot. Still, using the iphone convinced me that for portable internet there was nothing beating it. My resistance wavered and then completely collapsed.

I’ve had the phone for more than a month now, and while everyone and their brother has reviewed the thing I can’t pass up the chance to add my input.

So, how do you like it? Is a question you hear a lot when you use your iphone in public. Here’s my answer:

It’s like having the most beautiful, sexy girlfriend in the world, with the unfortunate habit of occasionally puking in your mouth when you kiss her.

What I love:

  • It’s a great little browser in your pocket. People bitch about it not having flash, but I don’t miss it.
  • Even if you have a poor connection (which is most of the time, see below) it will download voicemail so you can still get it.
  • It’s an iPod, albeit missing some features.
  • The screen seriously rivals paper. It’s that good.
  • The glass screen and overall build quality. No creaks, no fragility, just a solid gadget.
  • You Tube is far more fun than I ever thought it would be.
  • If you get a call while listening to music it will fade & pause the music when you answer, and unfade & restart the music when the call is over.
  • Even though it has no push email, IMAP email with Gmail is actually a better solution than Gmail on BlackBerry.

What I hate:

  • The iPhone hangs onto a call about as well as my 77-year old father hangs on to a greased pig. If you’re standing within site of a tower you have a chance. Otherwise, all bets are off.
  • That is, if you can get the call started in the first place. ATT seems to have simplified busy signals, disconnected number signals and call drops all into one “Call Failed” error on the phone.
  • The signal strength meter is more of an “estimated recent signal strength, sort of” meter. I’ve gotten and kept calls with one or even zero bars, and have also had calls drop unexpectedly with 5 bars. Go figure.
  • Bluetooth is a technology to be played with, not used. The relationship between my iPhone and my Jabra headset is more erratic than Brittany Spears relationship with reality. The two will spontaneously decide not to talk to each other and will need to be re-paired.
  • The glass screen provides zero tactile feedback, and is fairly picky about how hard you tap it before it considers it to be a “good” tap.
  • Occasionally my iPhone will take a nap like an old man dozing off in the middle of a story. Because you can’t tell this is happening until you’ve been tapping away at the screen trying to get it to work, when it wakes up there’s no telling where the game of iPhone roulette will end.
  • The iPod part of the phone doesn’t sync the skip count or last skipped data for songs. So, if you’re trying to make use of iTunes’ elaborate smart playlist feature to filter out songs you skipped through, you’re out of luck with the iPhone.
  • For whatever reason, my iPhone takes forever to find and connect to my home wifi network, and will never prompt me to connect.  It will often shows the signal strength as one bar, even when I’m standing next to my wireless access point. Other times it’s 5 bars on the other side of the house. This happens sometimes at other places.
  • Sometimes my iPhone will repeatedly and with great urgency ask me to connect to networks I don’t want to connect to.  We have wifi at work. It’s very locked-down and PDA’s are absolutely not allowed so I really don’t need my iPhone bugging me to connect. I really wish Apple would make an “ignore this network” feature, for places where there is wifi that for whatever reason will never be used.

Overall I like the device, but the relationship is love/hate.  That’s why I say it’s like having a fantastic girlfriend who barfs in your mouth - most of the time things are awesome, but when they go bad it’s such startling, frustrating experience it has me emotionally gagging on the phone.

Let’s hope the new iPhone 2.0 software coming in late June (I’m expecting late July) will tip the balance a bit.


Checkster Not Worth The Effort

A while ago I posted on how I was trying Checkster.com as a tool for doing a 360 degree evaluation. It seemed like a great tool, although it also seemed like it had some odd limitations, namely a maximum of 10 people can be invited, at least 3 have to respond before you can see any results, and there is a 7-day limit on time to respond.

The bottom line is that this doesn’t work very well. 10 people max with a minimum of 3 to see results means you have to have a 30% response rate, which is pretty darned high. For example, my experience with Linkedin is that about 10% of the people I invite, who I know, who I’ve personally invited in person with an explanation of what Linkedin is actually join. Expecting 30% of the people who receive an email asking them to spend 5 minutes describing a coworker’s strengths and weaknesses to actually follow through is extremely optimistic. Unless, of course, you only invite folks who are your friends or who work for you, but then what’s the point?

The 7-day limit is also silly. A week is not very long, especially in summer when folks are on vacation. A month or even 90 days would be much better.

Lastly, while there is a “resend email” button for each person you’ve invited, you have to do each one manually. That’s a heck of a lot of work.

Here’s what Checkster needs to have to be a real tool with real usefulness:

  1. Ability to invite more people. One hundred would be a good start. Let us upload the list in .csv format.
  2. Send tickler emails automatically every week to those invited to respond, with an option for the individual receiving the invitation to say they’re opting out.
  3. Ninety day limit on checkups rather than the 7 days they have now. If the fear is that too many checkups will be going on, then limit us to two per year.
  4. This may already exist - I wouldn’t know because I haven’t gotten a checkup to complete - but give us a link to the results that we can send to others.

In the mean time, does anyone know of a tool that has these features?
