Anyone used any of these components? And could give some feedback about them.

Never even heard of them.

Audison makes a very high end line of components however they are more geared towards sound quality. The benefits of this are not needing a high powered amp to get good sound as most sound quality components need no more than 60 watts rms. The drawback of sound quality products is they aren't very loud as most audiophiles listen to music at low volumes. In the end a sound quality product tends to give a softer response.

I personally prefer the POLK MOMO components as they crank and are very durable and handle a lot more power than they are rated for. They also sound incredible in my MX-3 as the imaging of the components in the factory location is incredible.

Thanks chew. I knew that the amp was a high end amp and I'm familiar with some of the benefits of high currebt amps. Most audio enthusiasts aren't aware that one could get just as good if not better SQ and SPL from 50 watts as that from twice that amount of wattage from a lesser grade / quality amp. 1000 and 2000 amps don't really mean much if the amp/speaker effeciency ratings aren't very good. All that means is that one would need tons more power (watts) to approach the same level of SQ / SPL.
There were a number of amps I was looking at, Audison being the forerunner at this point. My main concerns is that it doesn't have digital inputs and my source unit wil be a car PC. Therefore, I'm not sure what my best solution is in going from the 5.1 AC97 codec sound from the motherboard to the amp. What's the line voltage from a typical MB? What's the line loss expected in running RCA's the length of the car from the PC up front to the amp in the rear, questions like that I'm not 100% on.

Ideally, an optical input 5.1 channel amp with a built in DD, Pro Logic II/EX, DTS/ES, THX or some combination thereof as far as processing the 5.1 would be the perfect answer. I already have a 5.1 amp (Performance Teknique ICBM 5.1) that has most of these features, unfortunately the vender failed to ship the necessary IR remote control reciever and IR remote control that is required to manipulate/control/configure the digital input. Three weeks of trying to get them to come good on their product has been hopeless. If I was more up to speed on the various amp selections out there that utilized a mini plug in IR remote reciever and a small wireless IR remote control, I'd try to source one of those since they may all be of a similar nature. Without which the amp is just a glorified expensive doorstop.

These are some of the other contenders. Emails to these offshore company hasn't produced any product availability, pricing or shipping info.

Anyone knowing something about these would be helpfull. BTW, I have had contact with the 3rd company in Germany. They will not ship outside EU and I would need a 3rd party in EU to facilitate this.

Audison are amazing amps. However, they are pretty biased towards Class A operation, so they will draw an a-- load of power. You'd definitely need to upgrade your charging system if you were using Audison for the highs and subs. If you just went Audison for the highs, then a Class D for subs, you would probably be OK.

And looking at effieciency of speakers (even if we're looking at real world A/B comarisons) doesn't mean much when we're talking about high SPL. Efficiency is measured at about 1 watt. When we're talking total SPL of the system, you need to know what the speaker is doing with that power. Some high efficiency speakers will go into compression far before a high SPL speaker would, so that by the time you get into the several hundreds of watts, the less efficient speaker may pull ahead in total SPL for a given wattage.

What Chew says about concert level sound from 60 watts is true. However, consider that an Audison is A) also underrated in its power and B) the Audison will approach clipping much softer than other lesser amps. The combination means you likely wouldn't hear the distortion until your "60 watt per channel" Audison was doing more like 100+ watts at 14 volts.

And what is the reason for wanting an outboard DAC? The internal DAC's in most CD players have been more than adequate for several years now. If it's to go 5.1, I'd wonder why you're looking to go 5.1 in a car. You're not a 50 year old ricer, are you?

I believe JVC has some dvd/dvd-r/cd/cdr-w/mp3 decks that offer optical and or digital outputs. I would personally lean more towards this direction for 5.1 versus a pc. Also I might add if your really into sound quality a 30 band 1/3 octave equalizer per every 2 channels of amplification does wonders.

I'm currently working on a SQL car at the moment although its not an mx-3 I might post some pics when its done. It will be using 3 kicker cvx 12" subs in a ported custom enclosure, a kicker zx 2500.1, a kicker zx 850.4,
2 sets of POLK MOMO 6 1/2 components, an eclipse cd 5000 headunit and 2 kicker OEQ 30 band 1/3 octave equalizers, still havent decided what to use to clean up sub response. Most likely an audio control product.
