    Adding VU meters to DIY Amps

    Fred, hello and thank you! Looks simple enough to hook up, but please anyone chime in if I'm overlooking something in terms of my assessment of how "simple" that hook up actually is.

    Anyone have any suggestions for a suitable preamp (passive or active) that matches well (preserves the sonic neutrality) with the basic Purifi build (Hypex and Purifi board only)? My only requirements are a remote and three inputs (doesn't matter to me if balanced, unbalanced, and it would be a...

    Adding VU meters to DIY Amps

    Hello, How difficult would it be to add VU meters to a Purifi amp assembly I recently completed (https://www.audiosciencereview.com/forum/index.php?threads/diy-purifi-amp-builds.10478/)? I don't know where to start and so I'd be quite grateful for any suggestions and/or directions. Cheers.

    Does anyone know how to add VU meters to this build? Or is that question deserving of its own thread?

    I too stumbled across the "VTV" Purifi amp during a recent Google search. Would I be correct to believe that its primary differentiating characteristic is that one can use it to "roll opamps" should one choose, or not, IOW still be able to get it to function as a Purifi-Hypex only unit...

    Excellent. Now I get it. For me it's the simplest explanations that are the easiest to understand.

    What continues to have me befuddled (in a good way) is trying to understand how "little" Class D amps are able to perform as well as the Class A/B ones that have hulking huge capacitors on board. I was poking around a Mark Levinson ML436 the other day and, whoa, it's got four of those big blue...

    Where does Amir post the "burst" results?

    I'm thinking that with the low sensitivity of the Revels perhaps they might benefit from 800W continuous and up to 1000W burst. What is the equivalent burst spec for the Eval-1/Hypex?

    Man-O-Man that is nice Roberto. I want to try one of the power supplies you used. From which supplier did you get that?

    Jim, if you have experience, can I trouble you to recommend a paint brand or type? Would it be the spray can variety? I know nothing about painting bare aluminum but I'm willing to give it a go.

    My enclosure will be assembled from spare aluminum parts I bought at a nearby scrap metal dealer ($17). I'll do my best to make it look as professionally slick as possible but I'm not out to win any awards.

    My goal is to determine if the Purifi gear, at stock settings, creates a "synergy" (as I alone define that word) with any of the speaker pairs "better to my ears" than what I currently "enjoy" with my existing all-tube amplification setup (PrimaLuna DiaLogue Premium amp w/ eight EL34s + six 12au7s).

    JimM, I am testing on three pairs of floor-standing speakers, each with differing specifications and sonic characteristics: Revel Ultima Salon1, Polk Audio RT600i, and ELAC FS407s. The test room is 27x17x8 (3672 cu ft), carpeted, dry walled, dropped ceiling. Sources: no preamp (for now, even...

    Regretfully, I am likely not the typical DIYer who uses this Forum. I don't know how to read a schematic. I did not check for continuity between board inputs. I did not check the output voltage from the SMPS. However, I learned here that I should have done those things, and so I will...

    No I did not use the ampon/fatal connections. I will try doing that though. I am still trying to get my head around the benefits.

    Not in a box yet because I was anxious to just get her up and running, so be kind, yes it's crude and sloppy but it is my first ever DIY amp build. I have the aluminum plates and screws to complete the box, just received the drill bits for cutting the input and vent holes, and so I will...

    My build works as predicted. Strong control over low to mid bass in my system. Sounds good to me as-is stock out of the box.
