I must admit I like the metaphor.
I haven’t tried the HEK Stealth yet, but I own both the XS and the HEKV2.
My initial plan was to simply replace my XS with the HEKV2. However, I quickly realised that I like them for different things, so I ended up keeping both.
The XS is definitely more fun, whereas the HEKV2 is a lot more sophisticated. Both are great at doing their thing.
If you happen to live near a Minidisc or an AddictedToAudio etc, that’s a big plus. They have quite a lot that’s available to try. Otherwise, yeah - buying used is the way…
