Thought this would be a good idea for a thread Make sure you give reasons too. For me. Best: Allen and Heath Zed-R16 - Made my mixes come to life and made headphone mixes simple. Mesa Rectifier cab - Although expensive, it gave me the guitar sound I was always chasing. ISA828 - gave me 8 superb preamps with superb conversion Focal Twin 6s - again expensive but let me hear everything, especially low mids. Ensemble Thunderbolt - What can I say, sounds amazing and has the perfect feature set Studio Projects T3 valve mic - amazing quality for the price (or any price) Palmer dacappo reamp box - Just works. Clear and clean and excellent gain staging Fiio E07k headphone amp / DAC - beautiful sounding headphones everywhere I go. Headphone out on my Macbook pro sounds like ass compared to the Fiio. Worst: Radial X-amp - total piece of shit that had such low output that you had to clip DAC and input of the X-amp to get enough level to the amp. MXR Wylde overdrive - not great sounding and the pedal switch broke on 2 of them I had. Neumann TLM103 - not a bad mic but never really got on with it. Even prefer an sm57 on vocals. ENGL powerball - as we all know, mudball Pearl Masters - toms would ring/hum through every song. Replaced with Sonor S Class which is awesome Universal Audio LA610 - good but not worth what I paid for it. Very limited headroom and easy to clip. If I could have the money back there are plenty of things I would prefer for the same money. Currently for sale Yamaha i88x - on paper this was a really good audio interface. Unfortunately Yamaha's M-Lan drivers were terrible and eventually Yamaha just gave up on it before they got it right. I'm sure I will add a few more things to this list when I think about it. Really looking forward to seeing what other people post here.
