@nickgoatley I just completed your survey.
First, I applaud your enthusiasm and intent!
Some feedback for you, from the perspective of a marketing pro w/MBA and 20+ years in reasearch-based product development... Your survey is likely to provide you with data that won't help direct your design.
You've got very broad open-ended questions with free form text responses. These are difficult to decipher and compile into meaningful action items.
The range of focus is so broad from first-turntable to SOTA, answers can't lead to any specific direction. I'd suggest first narrowing your mission to a more specific use case(e.g. first tonearm buyer with turntable costing under $XX) and restructure the survey with assistance from someone experienced in marketing research in general and survey design (maybe a professor at your university?). Questions about features will yield more meaningful results if structured as selections from a list, rankings of a list of features, or scaled responses(e.g. not important at all...very important).
Try imagining the tabulated dataset and how you'll take action with that result. If you're unsure, then the question isn't finalized. Best of luck...this is hard! Cheers,
Spencer
