    Hello good folks,

    I just received the PB3. I love the sound but mine rattles when I shake it gently.

    Anyone else experienced this?

    I think I could live with it unless it is broken.

    Thank you.

    Thank you for the kind offer Paul.

    Unfortunately, I purchased the amp as "open box like new condition" from a retailer so I cannot imagine it is covered by a warranty.

    I can return it. I just really want to keep it and if I knew the rattling was not something damaged inside I would.

    Many thanks.

    I returned one in the UK as it rattled, think it was one of the first and I posted about it in the thread here.

    Worked perfectly and sounded great but I was worried the rattle was something metal that could cause a short circuit later on, you should still have a 30 day warranty with open box unless stated otherwise?

    Thank you for your reply.

    I knew I had read somewhere about another rattling unit. I was starting to think I had imagined it.

    Yeah, I sent mine back and I am waiting for a refund.

    I loved the sound but was kidding myself if I thought I could live with the rattle.

    After about a year of ownership, I am still really liking this amp. In balanced mode, it has transformed the sound from my Sony Z3. I used to use the Z3+ as transport for the Mojo, but the improvement the PB3 brings means I often don't both with the Mojo anymore. I don't know why Sony crippled the Z3+ with such a poor amp section when it's dac is decent.

    Just ordered PB3 will be pairing it with Opus1 and LZ A4 iems' with the balanced cable. I was disappointed I will have to use the single ended out on the Opus1, but I really like having a analog volume control and I was having to push the Opus to about 80% volume with the LZ A4s. I really like the LZ A4 they have way better soundstage and bass over my Westone dual driver custom iems', I just miss the custom fit. I am hoping the bass will be a little more dynamic and it brings the mids up a little, but will be happy if it is neutral and just gives a little more headroom.

    PB3 unboxing video. Burning in the PB3 (not going to debate whether it needs it or not...) and a couple of cables right now.

    Hi , when the PB3 will be available on the Ibasso website ? Thanks in advance .

    Isn't that strange? They've never, ever, had a good webmaster, in my opinion, but I suspect there's more to this mystery. Perhaps (and I'm only conjecturing) the retailers who appear to have exclusive rights to sell it, currently, helped to fund its R&D. That might explain why there are no direct sales from iBasso, as we've always seen in the past.

    Looking to re terminate a cable to 2.5mm for the balanced out on the PB3 can anyone confirm where the R+ R- / L+L- go to on the trrs plug.
