Without going into all the technical details:Used correctly (assumes knowledge of acoustics, hardware and software etc), this mic can be easily used for professional class recordings, certainly including vocals.I also have an AT2020, and while it's also excellent for recording, I like the "high pass" filter which rolls off the bass frequencies nicely, especially for vocals. The additional surface space of the cardioid pattern in the AT2035 vs AT2020 does seem to me to bring a different tone, which in my view lends itself well to some voices (hard for me to quantify this exactly, but it seems a little more "bright" in raw recordings).Of course with an array of high end plugins and gear, you can make even mediocre recordings sound much better, but for professional level recording, there is a lot of factors which will make the raw recording significantly easier to "polish" at the Mixing and Mastering stages, by getting it right from the start (includes having the right sound isolation and acoustic treatment, gear/DAW etc in the "studio" - including "home studios").The AT 2035 I've found is great for recording vocals (singing, voiceover etc) and acoustic guitar. I've yet to try it with stringed or brass/woodwind instruments, but would expect the quality to be in the same region.NOTE: This Microphone needs "Phantom Power" to run, and uses XLR connections, so this is NOT for use with USB directly, you need an Audio Interface with the XLR capability and Phantom Power to work. Personally, I MUCH prefer to run with a Thunderbolt capable Audio Interface, and use a Resident T4 for example (there are many to choose from) which is a Thunderbolt 2 interface, hence many times faster than USB 2.0 and USB 3.0 (idea being the "latency" is much better via Thunderbolt vs USB - depending on the PC set up and the type of Audio Interface, this will vary, but we're talking multiple, sometimes 10 times faster - so this is SIGNIFICANT - Note: Macs etc run natively with Thunderbolt).Re if you want to run the AT2035 through a Thunderbolt interface on PC, you will need a motherboard which is Thunderbolt capable, and often requires a specifically dedicated Thunderbolt card for the particular brand and type of motherboard to work, PLUS with the enabling software to allow the Thunderbolt to work. Reducing the time it takes for your signal to be processed, and for you to avoid "lag" in hearing the result (if it's delayed too much it can be VERY distracting if singing/playing for example), I'd highly recommend getting the best gear you can, and also if using a DAW (Digital Audio Workstation), getting the right "ASIO" software, and also minimizing all active programs to optimize CPU/RAM and Storage I/O (Input/Output) rates.Also, getting a quality Audio Interface will allow you to record with the sample rates and quality level you desire, which if quality is important, will be critical to the end result.So, if you want to get the most out of this mic, considering pairing this with some of the above supporting aspects to getting a great recording, this mic is certainly good enough for high end home studios to get professional class recordings, and at a great price point.
