Earlier this week I had an opportunity to listen to a DD S4 amp. It was pushing a 6.5" component set up-front and one ported 12" in the trunk. Color me impressed, it sounded very good to my ears.

I was just curious about other's people's opinions on the DD amps.

*Are they reliable?

*Are they expensive?

*How is their customer service?

The 4ch amp is rated at 100x2 and 200x2. Are there any other amps that can perform similarly for lower price? Just trying to weigh out all my options here by using ya'lls keen sense of cost vs. performance.

What I really like here is the idea of simplicity. Headunit, amp, a set of comps, and one sub. I'm not looking to compete, but I am looking for quality music listening!

Thanks guys,

I was wondering this too. I've seen them on their site, but never saw any reviews or anyone talk about them

I saw a Z1 explode in front of me back at dB Drag Finals a few years ago...didn't exactly give me a great impression of them, though I'd love to hear that push/pull EL34 amp that costs $5k that they started building recently...
