    If I buy a BT 5.4 transmitter/receiver for my old PC will my old BT Headphones (BT 3/4?) Controller (BT 4 prob) get any benefit from it ?

    Thanks

    I'm not that knowlegable about Bluetooth, I believe BT 5 is backwards compatible with BT 4 but you won't get any improved performance.

    I'm actually looking at buying a bluetooh receiver DAC to connect a phone as source to an old Denon amplifier and I also bought this transmitter back in January to let me use the opean ear headphones in the second image, it worked really well.

    The BT standards as they increase numerically tend to offer greater reliability better power consumption and higher transfer speeds but the older device while it should connect won't be able to get the benefit of faster speeds as it's limited by it's own electronics, in your case better power consumption is probabaly irrelevant on the PC end of the deal and the headphones will still consume however much power the consumed before.

    Also isn't 5.3 the current BT standard?

    This is the DAC that I'm thinking about for the hi-fi we could continue to just stream via the TV but I need another DAC for that so I can use the TV's optical out.

    Thanks... yes I'm trying to use an old amplifier/speaker set up to stream music without using a phone - which is how we do it at the moment.

    I've ordered a card for the pc with Wifi 6/BT 5.3 and was looking at my options... think Chromecast Audio would have worked well for me but they don't make them anymore.

    Had a read around, the bots told me that higher versions will generally work with lower version but you'll miss out on the improvements...

    Meaning BT 5.3 will work with BT 4.2 but they'll use the highest common standard BT 4.2...

    In order to take full advantage of BT 5.3 better range and more data for high quality audio transmission you'd need to upgrade the BT 4.2 device to BT 5.3

    How are you getting the audio out of the PC?

    From what you're saying you have speakers and amplifier but are these connected with an analogue connection to the PC, like taking a headphone jack out of the PC and feeding into the amp AUX port using RCA connectors?

    Or are you trying to use the computer to Bluetooth pair to a DAC like in my third image so that there are no actual wires from the PC to the amp/apeakers?

    Yeah that's what it told me as well, as I said I don't know a lot about BT those headphones in my second shot above are really the first time I've used BT for an audio device, they are good on a flight as they don't stick a rubber bung into your ears and you can sleep with them on, also handy when sitting in a hospital queue my daughter wasn't well when I was there and she kept borrowing mine because she forgot to bring the ones I bought her.

    I've really only used bluetooth in the past for peripherals like mice and keyboards and never really liked the experience because of the lag in the old days, these days I rather use wifi connected peripherals.

    In the UK I have been using optical out on the TV with this DAC below for a long time this connects to the AUX port on my amp via the RCA ports the optical SPDIF cable connects at the back of this thing, it's been great for my UK TV audio.

    In the Phils we connected the 3.5mm headphone jack to an old Sony music centre and then later to a Konzert soundbar but it's a **** solution which is why I'm taking some proper kit out with me in a couple of weeks.

    I'm buying a second Neoteck DAC to take out to the Phils as I bought a new Sony TV over there about 2 months ago.

    I also bought this ancient Denon on eBay last week (£109) my existing amp is a 25 year old Denon but this new one currently being tested in my system here and is going out with me soon, it's absolutely great. (the picture is my eldest daughter Gemma when she was about 7 or 8 years old 30 years ago).

    Bought a pair of Q Acoustic 3020i's as well which are small enough to fit in my luggage but sound as good as (possibly better than) the floor standing 25 year old Tannoy Revolution R3's this one is sitting on.

    [​IMG]

    The whole kit is really for my daughter who loves music, these little speakers sound wonderful with that amp.

    This is everything set up here and testing with Agsunta on YouTube which is one of Janna's favourite OPM bands.

    Another BT issue that ps me off - the very loud announcements you get when connecting - seems BT - DT DEVICE FOUND or whatever is always shouted out!

    Is there a way to control the volume ?

    Look a good buy for music listening - Practically deaf in one ear so tend to buy the in ear pods so I can listen to TV with the one good ear and "just" hear wife with the other when watching movies etc... both on for music :D

    I'm looking at a DAC to go with my Sennheiser HD599SE headphones. I'm gonna rule out Bluetooth simply because it cannot handle FLAC/Lossless - Bluetooth compresses the audio signal (although I do have a Sennheiser HD250BT Bluetooth headphones for casual listening). I have a Tidal music app subscription which plays music in full Lossless format, so to get the best sound, I'll need a wired setup, from my laptop and/or iphone.

    2/3 on my shortlist:

    Audioquest Dragonfly
    Ifi Zen DAC V2
    or the newer Zen DAC V3

    Leaning towards the Dragonfly.

    edit: It seems there is DAC is available over bluetooth according to this:

    https://www.whathifi.com/advice/what-are-the-best-bluetooth-codecs-aptx-aac-ldac-and-more-explained

    Sony have the new LDAC which supports a max of 990 kbps/96kHz/24bit.

    Rob in my first post on this thread third image that is an LDAC Bluetooth receiver that will plug into a hifi amp, it'll let a phone be the digital source and do the conversion prior to the amp.

    I used to convert any FLAC files to mp3's using "dBpoweramp Music Converter" as my ears are not as good with high frequencies any longer. This program also converts YouTube videos into audio files, too, Rob. :like:

    Bit too pricey for me but I'm told these are good:

    upload_2024-5-10_13-9-27.png

    They've got the streaming functionality and the ability to take the audio over the lan or wifi rather than BT.

    Next on the wish list would be this one, probably do me as I have an old (very) amp ...

    I was watching a documentary/advert on Linn the other day, the legendary Scottish hi-fi company, they were one of the first to switch away from cd and dvd to hi-fi quality streamers, I might look at one of the ones you mention John although for us the TV and phones are a good enough source most of the time.

    Don't think so, my headphones do the same they say connected and disconnected although they respect the current volume setting they get louder or quieter by pressing finger to the ear buds.
