Try the WS99 with a Headstage Arrow. Fantastic bass and keeps the whole sound spectrum intact. The SZ1000 is good too as the mids and highs are better compared to the nutso SZ2000.
That said I still like the SZ2000 more😊
The Cayin has a fantastic bass boost and a huge soundstage and will drive the SZ2000 and orthos like MadDogs to distortion with a huge reserve of power and most importantly a more refined sound than the E12.
I backed LHLabs on sheer blind luck and so far have been very happy with the product. Of course, there was always a chance it would end in tears but at this point in time I am very confident in their ability to deliver.
