Hi audiophiles, I need advice on my setup. I need a setup to play music, do streaming/recording and general internet stuff. These are the equipments I already have: 1) Rode NT1-A condenser microphone (with pop filter, shock mount and XLR cable) 2) Focusrite Scarlett 2i2 audio interface 3) Sonodyne IA 6410 multi-channel amplifier (4.1 channel mode) 4) Sonodyne Genie 1 micro monitor speakers. I have 4 of these. 5) Sonodyne Subwoofer SPW 8S (Note that the Sonodyne equipment above is a clickable link... it takes you to the manufacturer's page where you can read the specifications.) ________________________________________________________________ I have 3 questions: 1) Any advice about the headphone? I am going to get my headphone second hand, and I'm choosing between Sennheiser HD 598 SE open back, Sennheiser HD 598 CS closed back, and Audio Technica Ath M-50x, all for a similar price. I'm leaning towards the Sennheiser HD 598 SE, because I work mainly in my mostly-quiet room, so I think open would suit me better. 2) Do I need the boom arm, or can I do without it? (the shock mount that came with the Rode microphone seems to require to be plugged into something.) Is there an alternative to a boom arm? (If I do need a boom arm, I'm thinking of getting the Rode PSA-1 boom arm). 3) Most important question: What do I do for speakers + amplifier? Long story short: I have the Sonodyne speakers and amplifier as leftovers from a restaurant that I ran a year ago. Should I sell them second hand ( If I sell them both I'll get around 300$), and buy something else (possibly second hand) for speakers/amplifier? Or should I just keep them and use them as speakers?. Here is a picture of the Sonodyne speakers + subwoofer framework I have: https://drive.google.com/file/d/1TLZTRrOT3qMFWdExKgcxsnue-GcYAt43/view?usp=sharing As you can see it was built for showrooms and is kind of bulky... I would have to hang it from the ceiling. If you suggest I keep the Sonodyne speakers + Sonodyne amplifier, how would I make them work with my setup? Would they be plugged into the Scarlett 2i2? ____________________________________________________________________ Thank you! I really appreciate your help, because I'm a complete newb at this.
