Feature:
with both xlr and 1/4 I/O's in conjunction with -10/+4db selectivity, the only thing missing would be optical & digital I/O's - HOWEVER - this is the device that one could argue makes digital realm recording obsolete.

Quality:
I had my previous 104 for several years without any problems. My favorite collaborator has one that we used in a band 20 years ago. No problems.....This device does everything the manufacturer says it will.

Value:
Get a deal on one of these, they're out there, and it'll be the best investment in your music that you ever made.

Sound:
I use in a home studio between a dbx DDP and a tascam cr-rw700, this is a must have device for home studio owners. Generally in lieu of a tube EQ in the final signal chain, it works equally well as a mastering tool or in individual track recording. Essential for giving life to acoustic rythems and synth based horn solos. If you could have only one tool, this would be it. I purchased it to replace my older model 104.

Support:
i've never required any support of any kind, the manuals are more than excellent.

Feature:
Well, there is the "Big Bottom" with this you can enhance (or destroy) the deep frequencies of your recording. And there is the Ecxiter with which you can enhance (or destroy) the middle and high frequencies of your recording. You can actually enhance or destroy your whole recording with this machine. When you use the Aphex 204, besides having good monitors, you need to know what you are doing.

Quality:
I think a company like Aphex does not produce bad quality.

Value:
Good value for money if you are know how to use it.

Desirability:
I have got it

Sound:
I give it a 10, The Best. Yes, it is the best of all these kind of processors available. BUT...read on.....

Ease of Use:
This unit is not easy to use. You need to be experienced to use the Aphex 204. It gets a 10 anyway, because if you know what you are doing, this machine is great, If you dont, thats your problem

Support:
I do not know, never needed them, therefore a 5

Overall:
Well, as I already explained, when using this unit you need to know what you are doing. This is not a miracle-machine. Just while writing this I am listening to an officially re-released Hendrix CD. It really seems this CD was remastered using the Aphex 204. And I am sure that the people who remastered this CD did not know how to use the 204. They made the mistakes that every beginner, or everyone who uses the 204 for the first time, would make. The Aphex 204 has power, but only in the right hands. So the Aphex in this case gets a rating of 10, but the people who used it on this CD get a 1. Because using the Aphex, and it seems they did, they seriously destroyed Hendrix´s sound in a very bad way.

Quality:
I'm very picky. The chassis is solid, the circuitry well designed. The only fault is that the rotary controls on the front aren't as smooth as they could be in places.

Sound:
This processor fills out my sound like nothing else. I'm using it to process my main outs, and my sound becomes dynamic and expressive. I can hear subtleties that just weren't there before. The bass is 'rounder' the midrance crystal clear and the treble crisp and sharp, without being annoying at all.

Feature:
it has what you need.

Quality:
I've had no problems with it, plus it's under warranty.

Value:
it's worth more than it's sold for.

Desirability:
It looks plain but it's such a fantastic product that it should be rated 10 all around. The job it does makes up for its average appearance.

Sound:
Will have your bass booming without clowding up,and making sounds you don't want to sound bassy,bassy (it's intelligent}.Will lift your vocals and other highs out of mix without effecting lows.Read and understand manufacturers discription.This item can compete with even the most expensive ones in it's field.

Support:
The manufacturers have a phone number you can call, for them to answer your questions.

Overall:
As long as i make music i will have one of these in my studio.If something happened to the one i have, i'd buy another. Read this again.

Feature:
there is NO STEREO LINK SWITCH and it will throw off one side of your mixes, I swear the knobs move if bass hits them, they are constantly moving on their own, no joke

Quality:
said it once, say it again... no link switch

Sound:
the sound is amazing, but READ ON

Overall:
do not buy, shell out for something that won't inherently ruin your mixes
