semi old school, non zed, esx quantum q802xi vs mtx 81000d on hertz hx300d, sq setup.

[RandomBeat]

So I picked up this amp locally, off craigslist, after reading the entire 119 page old school show off thread. I know its not zed, but it still seems extremely solid and well built. The amp came with its original box, owners manual, side plates, and plexi and aluminum tops. It really appears to possibly have never been used.

I'm trying to get back to more of a sq setup, so I also went ahead and grabbed a hertz hx300d off craigslist for 100 bucks.

My previous (and still installed amp) is an MTx 81000d, which is an old school powerhouse.

Enter the delimma....

I went ahead and hooked up the hx300d in series, at 8 ohm, to the 81000d. It sounds great, and I'm very pleased with it.

Its hard to track down realistic RMS values on both amps due to theyre age, but I'm guessing that the mtx is putting somewhere from 500-750 RMS to the hertz @ 8 ohm. Its class d, rested at 1000rms @ 4 @ 12v, 1500 RMS @ 2 @ 12v' but everyone with previous experience says they're quite underated, and its running at 14 v....

So do I switch to the esx, for sq purposed, as its design and ratings are seemingly much more heated towards that?

The esx is rated at 200 x 2 @ 4 ohm @ 14.4, and 850 x 1 @ 2 ohm. The hx300d wants 600rms, but some folks say it can take more....

The manual for the esx is all German, and I can't find a single page on it....

I'm tempted to just keep it in the box, but after listening to the hx300d on the MTx, I feel like it can take more power....

Opinions? Anyone have experience with the esx, post zed, quantum amps?

That ESX would be a killer amp on the front channels of an SQ system, but it would be a waste on a sub stage when you already have the MTX.

oh, and bump for more replies.

also guys, I forgot to mention.... the esx is supposedly, "class x"... any clue? The aluminum heatsink is inscribed with "digital power amplifier"...???

Yeah rich, I have been considering that option... hmmm. I may have to throw my old school tidal audio 6.5s in the front doors, and go ahead and parallel it with my Infiniti ref 6x 9s and 4" in the rear headliner..... (pics of the tidal below, they're carbon fibre cone, gotta be made by diamond or image dynamics...)

Yes, i agree the ESX should be powering a sweet set of speakers. the THD is so low at rated power - a sweet SQ amp.
