Thats a shame, considering the macro-tech series are such tanks.

I've had two. Never has a problem. The earlier ones were unreliable when they 1st came out, but most if not all have gone back to crown and had faults rectified.

Used mine (Itech 8000), at carnival for 2days on sub duty at full pelt and no problems.
In my opinion, one of the best sounding lightweight amps.

Another dude on here (venture sounds) swears by them.

I had 2 on ebay upto this weekend. Sold one but now decided to keep the other.
Listen to people who have used them rather people who listen to rumours.

I might know Someone who is selling one

I-Techs are around the very few of good sounding switching amps. For example they are much better in mids-high range than Powersoft K series. The general problem with the I-techs is the reliability especially tons of boards and connectors inside. Two of mine even did not survive a single transport by van to remote area of Romania...
The roads in Romania are crazy bad anyways.
Another thing is that I-tech has bit smaller power supply what you would except, so sometimes the long low-frequency tones are not so so strong. For example the PKN XD6000 beats the I-tech8000 in sustained power if we speak about low frequency response.

Be very careful to get older/used ones! They had multiple glitches previously which has been eliminated then by hw/sw changes. Old ones are on the used market cause the repair is difficult and big rentals rather work with newer amps fully covered by warranty...

Was about to come running to the itech's defense, then realised what I've used are XTI...

Really what Motion54 and U.Viktor said. I have three of these and they are good, powerful, nice sounding amps. 
You need to be careful when buying used, as the very early ones were unreliable and nearly ruined Crown's name. Over the years of production Crown sorted out the problems, and there are about half a dozen mods which have been made, some electrical and some mechanical. Things like ribbon cables working loose/ going brittle (which were changed later for tougher ones etc), and a few small components were uprated.
Internally they are very complex with lots of SMT components (similar to powersoft in complexity) and as such when they need repair need to be taken to the distributor or a Crown authorised repair centre rather than your local TV repair man.

We have had to repair booth I-techs, PowersoftK and PKNs previously. What was a surprise that Powersoft amps are really not so complex than I-tech. The amplifier part of Crown is at least twice as more complex than PowersoftK, probably this is the reason why the interleaved switching of the Crown sounds far better than simple Class-D Powersoft :-)
There are some parallel-connected small foil capacitors in the Crown , when one burns easily destroys the multilayer board and then pretty difficult to rescue the damaged board.
