In Reply to: RE: Jameco 5V 1A 'Transformer' Wall Wart.... posted by Ivan303 on May 21, 2017 at 17:43:08
battery supply is decidedly better sounding at the top. :)
My 24,000 mAh battery is not noticeably different from the Jameco transformer adapter(have not time A:Bing it). Jameco is better than the wall wart that came with the Pi, and the various USB chargers I've tried,so that did it for me for now.
And it doesn't need recharging every couple days (I leave the Pi on 24/7). Even now with what should be a permanent IP address, it still can be a PITA to find on my network(iPad finds it easier than the browser on my Mac Mini for some reason). Plus it doesn't have a 'power switch' ya gotta muck with the cables.
If this looks to be a permanent installation I'll invest in the 'Metal Box' and a proper LPS.
But then QOBUZ comes up with Hi Rez streaming (24/96 and 24/192) for an extra $10 a month. But only through the Window/OS-X player.
So maybe I'm back locked into a computer after all. :-(
That Jameco LPS has worse specs than many switchers. Pretty bad in fact in areas like ripple and voltage regulation.
And typical USB batteries have a switching circuit internally to boost the internal battery voltage to 5V....... So you're not really running purely off the battery itself.
That said, Jameco is much better than the cheap switcher that came with the Pi (pictured above).
One thing that can not be forgotten, switchers inside battery packs or not, about the battery is that it takes the Pi off of the the home AC system with all of the crap that's attached to it. And what with my 25 lb. DAC which is mostly power supplies, that might be of some benefit, and the Ethernet is somewhat isolated as well.
Running on the batteries at this second and it may be a bit better that the Jameco.
Streaming 'Turn Up The Quiet' w/ Diana Krall via QOBUZ because...
Streaming 'Turn Up The Quiet' w/ Diana Krall
Say it ain't so! She's still around? ;-)
unless one uses 'audiophile' music. ;-)
I never heard either of my TAS reviewer friends play schmaltzy jazz. :)
Classical was always the rule of the day. Which is likely why I really enjoy that genre to this day. JWC's vinyl collection was truly massive. I never experienced a case of "do you have...?" - it was always "which version do you want to hear?"
Want to hear some Berio or Panufnik?
I purchased one of Krall's albums to see what all the fuss was about and still don't get it!
Get a copy of the DVD "Live in Paris" by Krall.... Put it on your Big Screen TV hooked to your Main Audio System. Settle in with a good bottle of wine and watch the concert. If you don't 'get it' after this, There is no blood in your veins.
BTW - Seeing her Live in Minneapolis a week from this Friday...
that won't happen, but I did just add it to the Netflix queue.
OTOH, if I'm not found of hearing an artist's music, I doubt that watching them play said music will help much. Does she do jokes? :)
Not really a fan of concert videos, either. Have one(?) I think.
No way is this on my Netflix....
But now I discover that only once it's put in into your queue do you see that availability is "unknown". :)
Log in and follow this link:
If I can't stream it, I'm not interested...... Not available for streaming. You'll have to borrow one from someone. It's a very popular DVD.
and listened to the first minute of each track. Why does the guitarist always play the same simple twangy stuff? I think you're right about the wine - I need to drink a bottle or three first and perhaps that would put me in the mood. I'm totally sober now.
As for female pianists, I'm more the Liz Story type. I've heard her live at the Woodruff Arts Center playing the Steinway unamplified in a nice hall. Magnificent.
I have several of her albums containing wonderfully expressive and emotional original work. It is her music that stirs the blood in my veins. :)
It's an acquired taste...... If you really want to enjoy it, Watch the DVD.... If you're just interested in proving me wrong, just let me know. I can accept that.
and just exercised it. Again. Did you recall that I already have some of her music? Eyes not required.
For me, I can pretty much determine as to whether or not I like something in the first minute of hearing a work. I was strolling through some new albums on Tidal and listened to Rihanna's newest. Most of her stuff doesn't do anything for me, but occasionally I find something that does. From Anti , I like "Same Ol' Mistakes". And Katy Perry's latest single, "Bon Appetit". Well, I could do without the auto-tuned rap near the end. :)
In the classical genre, I discovered Howard Shore's Two Concerti . More nice stuff.
Musical tastes just vary. Widely at that!
One thing I dislike about her style is the mangling of many original work's timing. Examples are The Look of Love and The Girl From Ipanema . Has she never heard those tunes performed before?
When you compare those to that of Dusty Springfield and Astrud Gilberto , it seems her goal is to deliberately put a "lounge lizard" spin to the delivery.
Not my style.
Maybe she's into NAS storage, too. ;)
Don't play them much, even though we have TWO TTs, one on either side of a small-by-today's-standard TV.
Mostly stream classical from TIDAL and QOBUZ but have about 1,000 or more CDs to figure out how to rip and store.
I think people make a big mistake thinking lossless FLAC streaming is somehow sub-standard listening. Every improvement I make in either of my systems seems to improve the sound of lossless FLAC streaming, either QOBUZ or TIDAL. In fact, I am coming to the conclusion that, in some cases it may depend more on the CD player being used as to whether there is any difference at all between the original CD and a Lossless FLAC stream.
I'm pretty certain my current computer playback of a ripped CD sounds better than the same CD played on a decent Marantz silver disk spinner (DV-9600) outputted to the same DAC for playback.
OK, I really don't know that with any certainty as I am yet to purchase Ms. Krall's latest offering so as to do a proper comparison. :-)
As compared to my battery supplies. The difference in false brightness is evident to me - if not for you. Yes, for ten times the investment, you can match the battery's performance with a "proper" linear supply. I've owned two such 5V models. Just not worth it for me in the garage system. If you really want to do it optimally, you need to purchase an LPS-1 like I use in the main syste for even better performance.
I never have difficulty finding my RPi when powered up using iPeng in the LMS environment.
That's all I do.
Front and rear lights on my bike, last only 1-2 long rides mostly one. HR monitor, use it at the gym and on the bike, that would be 6 times a week and it doesn't last a week.
iPhone, iPad and my vape pen... (oops, never mind that one!)
Anyway, you get the idea.
And the Pi is located in an area which is hard to reach to unplug from the battery at the end of the day. I could get 4-5 days off of the 24,000 mAh battery if I just remembered to turn it off at night.
Vape pen. LOL
I have one too. Maybe once a day. After work with a cocktail.
but I keep misplacing it. :-(
Why only one?
If I were you I'd have one in every room.
I have about 12 of them. Lol!
Which reminds me, I have to recharge my front and rear bike light and my HR monitor for tomorrows ride.
Vape pen will have to get in line for a charger. =:-0
oh wait, you're talking about vaping the funny green stuff!
here's a song for you...
View YouTube Video
I can see why you only have one.
I'm talking about vaping nicotine juice. =-)
And the Pi is located in an area which is hard to reach to unplug from the battery at the end of the day.
That would be the case in the main system where I use the LPS-1.

I do and access to the garage unit is open. I also have several batteries in rotation. At least one is always fully charged.
I was pleased with using a Terdak linear with one of my former Touch players. I found that was equivalent to using battery power.
