iFi audio GO Bar - The Best Pocketable HiFi System, Bar None!

Go Bar from iPhone 15 Pro (USB C) streaming from Tidal.

When a playlist has an MQA song followed by a PCM song the Go Bar gets caught out and generates a bit of white noise over the music that lasts perhaps a second or two.

Anybody else noticed this ?

Are you on the bit perfect filter? i had this on the iphone 14 pro. had two solutions. One was to set to GTO filter and iirc downgrade firmware or utilise alternative cable.

I tried all filters and they did the same thing.

I have not tried many cables but it does it with at least three that I use for different situations so I didn’t think further than that, I might try one or two more to check but I don’t hold out a lot of hope with the relative standardisation of USB C.

I wondered about downgrading the firmware but assumed that the latest would have ironed out this kind of issue and the latest would be the safest pick. That said didn’t all the firmware options predate the iPhone 15 so presumably none have been implemented with the iPhone 15 in mind specifically.

It isn’t a huge deal for me, I just use Apple Music instead with the iPhone 15 and Go Bar combination, Tidal works fine on my couple of Android DAPs.

Have you tried to see if it does the same using Tidal through UAPP... I don't want it to be a problem with the Tidal app which I have read is not excellent especially for MQAs.

There has been an overarching issue with Tidal since the current update this week across multiple devices (not just ours).

As an example my playlists were unlistenable as of Friday, This was on my system that had no iFi product in the Chain and was using Roon. Windows Mini PC SMSL DAC etc.

Hopefully, this will be resolved quickly by Tidal.

Cheers!!

UAPP doesn’t exist for iPhones.

I used to use it on an Android DAP but gave up and use the native app instead.

OK hopefully you are right.

I did notice an issue with different file type songs not even starting to play on Android but nothing that resulted in noise issues.

Regardless I have a work around if there is a problem that app updates don’t fix.

Oddly, out of curiosity I tried the Go Bar with my Shanling M3 Ultra, I don’t really have a use case for this but was curious. On either Tidal or Apple Music the volume control from the DAP (with the sync volume setting on Go Bar turned on) was unusable and pretty much defaulted to maximum.

It seems that USB interaction between devices isn’t always absolutely reliable. I have had several situations where different devices just can’t be used together at all.

My iPhone 15 did a Tidal update a few days ago that hasn’t fixed the issue that was present long before that.

Perhaps iFi could pass this on to the programmers to see if there is a fix.

iPhone 15 Pro - Tidal - Go Bar = white noise switching between MQA and PCM.

I will certainly mention it to them, and if this continues much longer please take a moment and report this to our tech support, so there is a record of it.

My Tidal is still messed up this AM using Roon, here is a screenshot of what I am seeing from Tidal to Roon, very unusual...

This is direct LAN Connection, from Roon Rock to USB Pro iDSD Sig.

I tried rolling back the firmware to 1.70 and 2.20 from the current 2.40 and nothing made any difference.

Latest update to Tidal 2.107.0 and the issue persists, that is I think now at least three app updates that the problem has existed through and it might have done it with every version of the app, I haven't used the Go Bar with the iPhone 15 Pro until quite recently.

Seems like a USB compatibility issue to me. Oddly in a world where this sort of thing seems like it is a solved science with strict standards I have had incompatibilities and similar white noise problems with several combinations of sources and DACs that only swapping to a different source (or DAC obviously) could solve. No amount of messing with cables or waiting for app updates made any difference and the problem was repeatable just like this one.

I will have a look on the iFi website to report it but I am not concerned as I just use Apple Music instead but figure it is worth mentioning to them.

EDIT - logged info with iFi support - the outcome is not critical to me but it would be nice if a firmware update could fix it. I would imagine one of the techs has an iPhone 15 and uses Tidal so I would hope it would be an easy thing to duplicate :relaxed:

A rule of thumb for me personally is to never intentionally speak ill of another company's product or service, but for me at the moment, who never really runs into these issues Tidal is a mess on several different devices. On my MAC, iPhone has no issues...

On Android And Roon, messy the best I can say...:relaxed:

I continue to say I'm sure it will be sorted out soon! :fingers_crossed:

Cheers!!

Well that was pointless.

IFi supports best idea was I had the white noise background sounds turned on 😂

I replied but of course it is a no reply email so my reply goes nowhere apparently.

I'm a bit confused, if you want to PM me your ticket number I will try to look at it for you.

Cheers!!

I explained the issue as above which is very simply iPhone 15 Pro - Tidal - Go Bar = white noise switching between MQA and PCM and I added that the white noise played over the music of the PCM song at the same volume for a couple of seconds or so.

The reply talked about noise between songs, not at the start of songs and very specifically after going from MQA songs and starting PCM songs.

The extension of the idea that the noise was between songs not while a song had started playing was that maybe I had the phones background sound feature turned on and it was playing sound from the phone's background sound feature except I didn't know that was turned on, of course it isn't.

They didn't read my query properly, didn't understand it or just went through the motions and providing a fob off because they don't have an answer.

If they don't have an answer that in itself is a much better answer than a random stretch that I had feature designed to make background noise turned on and just happened to not have not heard the same background sound during other use of the phone outside audio.

I have a work around anyway and it could still possibly be a problem with the Tidal app, which again would have been a perfectly fine response as well.

I don't care, I have other options so it doesn't bother me, I deleted the emails about it because I have no intention of following it up. I logged it because it was suggested to here and I figured that might help others perhaps.

If you want to follow it up that would be grand but I don't have a ticket number to give you to assist that process sorry.

Appreciate your concern and professionalism, thank you.

You are quite welcome, I wish I had a better answer for you.

If this is happening only on MQA tracks (at the moment) this wouldn't surprise me, there seems to be a difficulty there for a bunch of devices. Speculation is that the changeover to all FLAC is creating problems for some devices, and by that, I mean source and Dongle, or DAPs for that matter. I think every manufacturer is kind of stuck in the MQA Switch Further (Yes that's an Insidious reference).

Without speaking ill, if Tidal would just stop sending MQA-encoded material this wouldn't happen, but it is what it is until they are done.

I will try to research it further. Right now my Roon wont even play an MQA track it *** right thru it, lol

Cheers!!
