After burn-in more than 300 hrs, IMO My HK6 not too much change compare with 100 hrs or 200 hrs, maybe I am lucky enough that my HK6 does not have any problems. Equipment: HK6 + Shanling M3S + 8 core pure silver balanced cable 2.5mm MMCX from NiceHCK Some Sources: 1. The look of love 2006 -...

Normally I just read because my English not good. Anyway, I like this thread. :gs1000smile:

After burning in around 60 hrs with my Shanling M3S, I changed from hybrid cable (Copper/Silver) 3.5 mm to pure silver balanced cable 2.5 mm and I tried to play around with the tip I found that HK6 step up to next level of mid sound (wide and clear) and a lot better bass.

I would say I fall in love with HK6 but I will keep SWIII for my reference :o2smile:

IMO, after 12 hrs burn in HK6 with my Shanling M3S, I would say overall soundstage, detail, and the vocal of HK6 a lot better than SW3 but SW3 still give the high treble and deep bass better than HK6 but let see after burning in 200 hrs I very curious to see how HK6 will change. I really enjoy...

Just got my HK6 today. First impression, HK6 together with my Shanling M3S give a very crystal clear sound with very high detail and wide soundstage, incredible vocal and perfect mid sound out of the box, only deep bass not good enough compared with my shockwave III.
