Three Stones MiniBox-E+ - Review of a Humble Sleeper (LOTS of PICs)

Yeah but sometimes can't details enhance musicality? I notice the extra details I hear with the ER4S increase musical enjoyment. I mean, If you can pick up a guitar line and how it adds to and fits into a piece of music it can enhance/improve your perspective of the song and it's enjoyment.

Did you post impressions or review in another thread?

I read someone already tried OPA627AP. I have four OPA627BPs myself but I suspect mine to be fakes (at least two of them) I will try them on my MB-E+ soon and see how it goes.

Pretty much any single DIP 8 JFET opamps will work.

That's for sure. The question is - will they work better than AD8065AR?

Better is not the word I'd use. I have used AD8065AR and AD8066AR very extensively against many opamps and kept using them both on my MB-E+ and STAX SRM-001. Each opamps have their merits and the difference makes them special, how you use them in combination with components will either make or break them. I even prefer the OPA2134PA over AD8620 which is quite surprising because the AD8620 is the more popular one.

But I will know soon enough when I put the OPA627BP to test

Oh yes, I should have mentioned that my MB-E+ replacement came in today. I am amazed that Fang actually paid USD$31.00 to EMS over the unit from NY to Malaysia.

And so I have a spanking new MB-E+ and the burn in ritual begins....this time it will not be too worrying as I spend most of my listening time with the venerable STAX SR-001 MK2 system. The MB-E+ & ER-4P will have a mountain task to regain that "listening time" because I am totally into STAX sound now

So just to keep up my progress, I am on charge #5 with the MBE+ (the replacement I got a couple of weeks ago), and it's still going strong. I am charging, let it run, recharging, as part of the burn-in process, and to ensure the battery situation has been resolved. So far, so good. Very happy.

Also, is it a good idea to let the battery run down to zero? I have read that you should recharge the batter right before it goes out. Any truth to this? Don't want to screw up the battery on this MBE+. Any advice would be appreciated. I could set a timer. Seems to be getting 24 hours or so on a charge (this is without much use, just turned on).

You shouldn't let a Li-Ion battery run dry - that was only good practice for old NiMH batteries, but is rather bad for Li-Ion and Li-Po. Charge it often, top it off, that's what they like best.

Some say that you should run it down every 30th charge cycle, but I think that only applies to laptop batteries with calibration circuits, not to the ones used in amps and MP3 players.

love my Minibox e+. I was coming from a PA2V2 so it was quite a jump. Using it with Yuin PK1s and especially the DT990 05 with the bass boost pressed it pounds on hip hop lol. Very overblown but hey its fun. Great amp.

Update:

The new batch seems to be quite reliable with the battery and charging capability. My MB-E+ was running way over 24 hours on single charge (with 50% load) and this is already way better than my previous unit which can only last 8 hours. Charging seems to be as per described now where previously the full batt indicator will pop up in less than 3 hours.

Looking good and rosy. Hope it will stay that way
