Greetings to the all knowing forum- I am in the process of setting up my first W/D/W rig, and wanted to leverage the groups experience in helping to pick the right gear for my situation. My stereo wet signal will consist of Eventide ModFactor and TimeFactor pedals. I feel pretty squared away on how I am going to handle all the wiring and routing for the Dry & Wet mixes, however I am stuck on what would be the right move to amplify and project the Wet signals with my Dry mix. I am split between using a power amp and passive PA speakers, or two Tech 21 Power Engines. From reading the forum posts, the Power Amp/PA speaker setup sounds very popular and effective choice. However, the simplicity of the Tech 21 setup seems nice, plus I save a rack space on my rig (a nice to have, but I do have the space if need be). My questions for the group are: 1) Does anyone have any experience with both setups, and have any thoughts to share on the pros and cons of each? 2) Which setup would have better sound quality? 3) If you prefer the Power Amp / PA speaker setup, what PA speakers would you recommend? 4) Are there any worthwhile options that I am not considering? Thanks again for everyone input and help, feel free to PM me with any additional questions that you may have. Thanks again, cheers! Signal Path: G&L Legacy -> 2 x Mark L Custom S10 + A whole lot of pedals -> Two Rock Custom Reverb v3 Stereo Signal: Effect send of TR Amp -> Mark L Custom S10 -> Stereo Pedals (L/R, 100% wet) -> Mark L Custom Stereo Line Mixer -> Yet to be determined power amp/speaker setup.
