Vinnie, bmoura or others:Does anyone know if Sony, in fact, fixed the inverted polarity issue? I don't see it specifically listed. I am running both the HAP and a phono stage I would love to have them both in phase at the same time!
Thanks and hope all is well with the new projects Vinnie!
Thanks. I read the firmware and no directly specified fix. I'll see you in Chicago! We can visit a bit, yes? (Appalachian Spring in DSD on the HAP right now! I haven't forgotten--bringing yours to AXPONA, I hope?)
Any chance you can share the minimum spec of the battery pack requirements so I can see if I can get something or get someone to built something similar?
Hi eso6686,Welcome to AC and the RWA forum!You could go with external battery packs - but you need to be careful. You need TWO 4-cell packs ... one LiFePO4 pack at 12.8V, and one pack at -12.8V. I would go with at least 1,000mAh capacity. You also want to make sure you have circuitry to balance each of the 4 cells in each battery pack, along with the other very important stuff like over-voltage protection, under-voltage protection, over-current protection, etc. The charging voltages (from the modded Z1ES) for the packs are +15V, and -15V. Linear regulated with resistor current limiting. All built in.I actually have made an external battery supply for a customer before (2 of the Red Wine Audio 10,000mAh packs, the same we used in the Black Lightning supply, so the play time on battery was well over 24 hours!). A 3-pin jack on the rear panel of the Sony connected the Sony to the external battery supply via a small cable. No need to switch the battery pack ON or OFF, or to connect an external charger. The modded Sony has that all built in and it was all automatic. Feel free to email me if you wanted a Level 3 mod with external battery power solution. We can work it out, but please note that I wouldn't be able to get to doing this for at least a month. But I am very confident that you will find the results well worth the wait. Vinnie
Thanks you very much Vinnie for the prompt reply.How would you compare sq wise between the Level 3 mod running straight from the wall without batteries vs the Level 2.5 Mod? The reason for me asking is because if the Level 3 mod running straight from the wall is basically equivalent to that of the 2.5 mod then I might as well go for level 3 mode and have it run from the wall for casual listening and switch over to run off the battery if I am in for a bit of delight or showing it off to a friend ..lol. Cheers
Don't know if this has been talked about yet, but can you add a USB output to this player to make it a transport? As well as modding the digital sections for better performance?I think this would be sweeeeeet....
Heard ya..... Thanks for the response and your time! I also wish you the very best on your new Lio. It looks to be a fantastic all in one'er, and an extremely well thought out design. Look out Devialet!!
Hi Vinnie.I have a very important question.: do the HAP Z1ES mods pass along a DC voltage when connected directly to a power amp? I am keenly interested in the JOB MONO 250 that iI read is DC COUPLED, whatever that means. I do know that my FOCAL ELECTRA wouldn't be too happy to receive that DC?This is my very first time to post to a thread so I apologize if there's anything I've done wrong,,, including my grammar!
