...is lithium ion phosphate iron batteries (LiFePO4 @3.3 v) directly soldered via wires onto juli@ sound card. Batteries are not inexpensive (about $15 each) and can be purchased from Tenergy. Charger was about $12. But the immediate effect was one of added clarity top to bottom, remarkably grain free. Very strong mids and bass. Soundstage got deeper, small details were very precisely revealed etc etc
Alfred (sonics) and hanssatink were the pioneers of this mod. I believe bertel and sondale also use batteries to power the juli@ digital power supply. All these inmates have posted on this mod here in pcaudio. Pls do a search on their names to get more technical info.
But for me @ the cost of about $50 (including shipping from California) this mod is easily the most bang for the buck I have done to cmp hw. To give you some perspective, to me, its equivalent to minlogon plus the effects of a linear power supply on the cpu plus maybe a bit more. It is that good. I really value clarity in the high freqencies and wow do the batteries give it to you in abundance w/o being hard or edgy. At first it almost seems as if you lose upper frequency extension until the real thing comes along---then its OMG. Also I placed my battery tray directly on the rug covered concrete floor and initially the sound was ill defined and boomy until I isolated the battery tray throgh normal audiophile methods then it was a whole new ball game. Yes I have wires all over the place, yes it is cumbersome to keep the batteries charged to 3.2-3.4 volts---all this is a pia but it is definitely worth it.
