Wanted to add my 2 cents.
I’ve kind of gone the opposite direction, getting rid of lots of low to mid-end gear in favour of a few items of high end gear (some might debate im still buying ‘mid end’).
I think there are basically two things to consider:
- Good music recorded on low end gear is always better than bad music on high end gear. The music is everything.
- I think there is a price point above which you are no longer really paying for improvement in sound (with regards to noise, distortion, imaging etc). You are paying for different ‘flavours’ or more/innovative functionality.
With that in mind, IMO, there is a big difference in quality between e.g a RODE NT1A mic and a TLM103, but less so between a TLM103 and U87 (note I am talking about quality of sound not whether they just sound different). You can probably swap the TLM103 for a slightly cheaper mic aswell, that was just the first that came to mind.
