I use my. BISPA since last night around 12 o'clock mid nite , it is already 12 hours still got power to drive my LCD X
I want to test how long can last the battery in my BISPA

My impression :
Source : IRiver AK 100
Amp : BISPA BSP - PHPA - 03 WS
Cable : stock cable with Furutech Rhodium 6,3 mm plug
Mini to mini Crystal Cable Dream Line DIY
Headphone : LCD X loaner
High : has rich detail and more presence , clarity is not so crisp like my LCD XC
Mid : like tube very sweet , natural and clean
Bass : very good bass detail and very good bass reproduction from 350 USD Amp
Separation : very good
Soundstage : is wide with good depth
Overall :
If you like tube sounding set up , this set up is the right choice
BISPA amp is very good in detail and clarity
LCD X is warm and smooth sounding Orthos
This combo has very good synergy
I am surprise that $ 350 USD amp can drive LCD X in very good sound quality
IMO
