hsu amplifiers not reliable?

[ekÆsine]

I've read the reviews of the VTF-2 MK2 from http://www.audioreview.com/cat/speak...0_2741crx.aspx and there are 2 people who say that after 1 year or more the amplifier fails on them. One person complains about having it fixed many times but with no success. I'm interested in buying the VTF-3 MK2. I assume it uses basically the same amplifier as the VTF-2 MK2 but with more power output. I'm worried about the reliabilty of the VTF-3 MK2 amplifier, even with the 2 year electronics warranty. $750 is a lot and I want to know that the product I'm buying is worth my hard earned money. What is strange is that the STF-2 reviews I've read don't complain about those amplifiers being a problem. The STF series subs use a different kind of BASH amplifer, I think. could that be the reason of their greater reliablity compared to the VTF series or at least why the VTF-3 has more problems?

Summary:
Sounded great when it was working. However, in the 4 years I had this sub, it broke 3x, the first two times it cost me $100++ for repair, and I had to wait two weeks to get the sub back from HSU. After it broke the third time I moved on.

Strengths:
Sounded good when it worked

Weaknesses:
Poor electronics.

Summary:
The VT-2 provides unbeatable sound for a low initial cost. I tested mine with the Stereo Review audio setup disk, and this unit provided clean, voluminous sound down to 26Hz. If you live in an apartment or a condo, you'll never come close to realizing its full potential.

On the downside, my VT-2's signal detection circuit, the one that turns on the power to the unit, failed after three years, out of warranty. There's a lot to be said for the simplicity of passive drivers.

Personally, I expect modern electronics to be nearly bulletproof; I've never experienced a failure in any piece of audio equipment I've ever owned - until now.

I've had three great years of solid bottom end with the HSU VT-2, but I'm disappointed with the electronic failure and the prospect of shipping and repair expense.

Strengths:
Low initial cost, clean powerful and balanced response down to 26Hz

Weaknesses:
Signal detection circuit failed after 3 years.
