After the thread I started on other options than my Eventide Eclipse the software comments got me curious so I downloaded these demos to hear whats happening in the plugin world. At this point Ive been listing for several days and I have not formed an opinion about any preference one over the other. They are all good!
To keep it as even a playing filed as possible I used factory patches for Medium Hall or as close to what was available. Only tweaking I did was to low the output from the plugin on a few as they were too loud compared to the majority . The graphics are not the actual setting I used just pictures I found on the web.
An interesting note is that the algorithm designer for the Exponential Audio Plugins R2 & Phoenix Revreb is the same man who designed the Lexicon Hardware PCM96 & PCM Native Reverbs...Michael Carnes.
Lexicon, the company impressed me as the demo of the PCM Native plugins expired before my iLok 2 arrived. In a day they had deposited a new 3 month trial to my iLok account.
The Verb I found most intuitive was the Softubes TSAR 1...very easy to get what I wanted quickly and with not much tweaking.....the opposite would be Aether, way to many parameters and not easy to see whereas the Sonnox verb is deep but makes more sense when editing IMHO.
All reverbs have some sort of tone shaping / eq but none have the scope that the Sonnox Reverb offers...handles like a scaled down Sonnox Eq. I found it very handy for shaping. Sure you can drop in Eq plugin before a reverb but this is all in one and cuts down on cpu usage.
Most plugins did not work the cpu much on my 17" Macbook Pro 2.4 ghz Intel i7 with 8gb ram, except the Relab LX480. Its a liitle bit more hungry then the others.
Ive left out alot but these are some of the best I found after a good deal of researching.
The patch from the Matrix 12 is an evolving buzzy 1 minute recording completely dry with no eq, compression or limiting. Personally I can't stand listing to the patch anymore after days of auditioning...going to delete the thing from the synth

. The patch does show off the verbs well as its quite dynamic. The recording is 44.1k @ 16 bits
All demos are ilok based except Aether & the Valhalla verbs which cut out after 45 seconds.
Please suggest plugins you think should be included.
The differences are subtle so careful auditioning with headphones recommended.
Enjoy

http://www.luminasounds.com Same preset was used as on the Synth patch except I change the wet dry mix to 60% wet as most plugins washed out the guitar at around 100% which the Synths mix level is set at.
