Network Switches

@atdavid

See here is the thing, when my battery is starting to run down in my BT headset, I know .... the sound starts to change. The bits are the same, but the sound coming out, you know that antiquated analog stuff .... ya, that starts to fall apart. I guess I should assume it was one of those "digital" experts that designed the analog section. 

Exactly !!!!!!!  it is the analog audio that is breaking up. NOT THE DIGITAL stream

On every set of BT headphones or earphones that I own, when the battery gets low, I get a warning while it is still performing perfectly, then another while still performing perfectly and  then it shuts down. At no stage does the digital input get interfered with or the audio 'degrade' . You need to modernize your equipment.

I am going to guess you are on the "young" side

Actually no. I was lecturing on modulation techniques in digital communications in the '70s. I was part of the test group for Quadrature Amplitude Modulation utilizing Trellis Encoding in the early '80s And my IQ of 164 got me into the higest levels of military technology development

Oh but I forgot...........   I am ignorant


@three_easy_payments

I couldn't agree more. Why won't you answer the question about routers and switches possibly introducing EM/RF noise OUTSIDE of the signal path just like any other piece of electrical powered gear??? The quality of the signal is not the end-all in audio. I'm still patiently waiting.

You must try to understand that almost everything can introduce EM/RF noise. Every single device from the audio server, through every device my audio passes through on the internet and then my exchange to my router to my DAC can. Dozens and possibly hundreds of devices. But none of those sites think it necessary to use a magic cable or a magic switch. You really, really ought to attend a course on digital audio, or research it yourself

As nobody in here will giive a yes/no answer regarding my original question I will just go with the experts' advice
And why does this forum allow so many of you trolls? You are just preventing me from finding a sensible answer

You must be kidding me, right??? No one believes it’s necessary to use cables or other devices to negate the negative effects of EM/RF noise that you finally concede can contribute to an audio chain via every source with an electricity source?? Seriously? Nordost, AQ, Isotek, PS Audio, Furman, Synergistic etc all have entire product lines to deal with EXACTLY this issue. No one calls it "magic" like you do - it’s all just reasonable isolation, shielding, grounding, and energy dissipation techniques that measurably work.

Why should I take a course on digital?  This noise has NOTHING to do with the digital signal.  Go do your own research.

I would respond, but unfortunately I have bullshit all over my shoes.

You know what people don't claim a 164 IQ in an internet discussion?  ... people who actually have a 164 IQ. They don't need to because it is evident in their communication.

I would save your lies for people who won't call you out on it. If you had an IQ of 164, that would place you approximately 1 / 100,000. Your reading comprehension issues are clear indicators that that is not the case.

p.s. that would be:

• 70s , not  '70s
• highest level, not higest
• Oh, but I forgot 
  

So let me get this right. You have an IQ of 164, but you were part of the test group?


It is interesting that you were "part of the test group in the early 80s. So exactly which group was this?

Can you tell me how many of those devices reconstruct a 100+ db dynamic range analog baseband signal?

I am truly sorry to all those in here who were trying to give me a sensible answer. All I wanted was a straight knowledgeable answer

But I really can not put up any longer with this ignorant, jealous moron atdavid

To be honest when my experts replied to me regarding these nonsense products they did also warn me that I would find idiots like him on any ‘audiophile’ forum.

Ok atdavid, I give in. You are the big man, you are always right, everybody else has to listen to you and your ears are so much better than mine, and your equipment is the finest in the world and you know ten times more than me about digital communications and...and...and

You have achieved your objective of wearing me down with your insults and general assholishness (did I spell that correctly?

and yes it was measured 164 (around 130 more than you, it would seem)

As I have my experts’ replies I no longer need to listen to his drivel

Bye
