    Feedback by 'bigcat39' on listing 'Shanling UP5'

    Shipped promptly. Packed extremely well. The device is apparently brand new! All the factory packaging and accessories had the appearance of having never been opened. I am beyond impressed.

    recommend a scope for this kind of audio work

    Wow, that really *is* a decent scope. Looks like a total clone of the Tek TPS series. I'd love to put it up against my calibrator and see how it does. BTW, I'm an electronics metrologist, any questions just PM me

    Which soldering ion has the longest longevity?

    Buy yourself a used Metcal station from fleabay, I have one @ work that I have used daily for 10 years, nary a hitch. Plus, it is soooo comfy. Very worthwhile.

    Headcode Case Source?

    Heh, I guess you are right, Nate. I'll try to post a pic tonight. And I am afraid that you are correct, Larry probably made the case from scratch

    av710 and onboard ac97 on XP

    I just installed an AV-710, and I would like to use the onboard sound chip to run my speakers. I'm using Foobar2000. Unfortunatly, the AC97 doesn't show up in the Hardware profiles in XP. It is enabled in the BIOS. So, if possible, I would like to use both.

    LME49710 vs OPA627s ?

    Hmmmm. I find opamps to be very much a matter of taste, However, there is no opamp that I know of that is faster than the OPA627. Speed being a virture and all. Looking at the specs, the slew rate of the OPA is more than twice as fast as the LME49710. I prize precision in a solid state amp...

    Buying a digital multi meter

    OK, one more time.... By trade , I'm an electronics metrologist. Also a EE. I have calibrated thousands of multimeters. I am here to tell you, Cen-Tech meters, if filled with lead, make a DANDY rowboat anchor. You ppl that love 'em so much..... open one up. Look at the soldering job. Heck...

    DMM for life?

    Yes, I am most certainly speaking of the older, unCarlyized 48 series. I have a 49G+, and it is miserable. Anyways..... The Agilent 34410 is the best bargain in benchtop meters in the world. I own 14 34401A, they are so stable I use one as a check standard for my 5720 calibration standard. STAY...

    Mapleshade modded Scott LK-48-B

    Ok, pics are coming. Tmarshl, would you post some pics of yours? First impressions: this is very much a Sony loving amp. The soundstage is simply wide open. As this device has tone controls, I have done quite a bit of adjustment of the controls, and it really is a plus to have the controls. I...

    This oscilliscope any good for audio?

    I agree with Tangent. "You get what you pay for" is very evident in test equipment. And, you get neat things like onscreen display of settings. I have sole access to a $50K Agilent DSO, so maybe I shouldn't talk....

    Where to buy the OPA2107?

    Samples IMHO are hand picked perfect examples. That way, real engineers who need them to do our jobs get working chips. And I WILL get into the debate. Taking samples to just save a couple of bucks is immoral @ best. And it ruins it for those that need it to do their jobs.

    What Power Supply for PPA battery charging?

    Well, my battery powered super maxed out ppa is nearing completion. I'm going to use a 12 cell AAA config, the calculator says 23.75V. Do I need a regulated switcher? Gawd, I hope not... this has been one expensive project! I was thinking of an open frame 24V switcher, just case it up. But if...
