    Maverick Audio DAC/Amp

    Also...I'll say this much, my Creative X-Fi Titanium HD has better analog sound output than the Maverick Audio Tubemagic D1. I tried op amp rolling on the Titanum HD and found the stock stuff to be superb.   Also, I've recently built the Pete Millett Jonokuchi, which is almost equivalent to...

    Maverick Audio DAC/Amp

    I was in the same position you were in Apoq. I bought some the two Burson op amps, and they would have a loud hum when placed in the U5 position. I was not impressed by the Burson op amps. If I replaced one of them with another SS op amp mentioned below, the hum would go away, but still close to...

    I am currently using Beheringer Audio Truth 3030A, which are active near fields. I need to find some cheap passive bookshelf speakers to test the speaker outs on the amp. What is seriously impressing me about the amp is like no harmonic distortion, what so ever. I have maxed the pot to max...

    Update #3:   Hey Rick, as always thank you so much for the quick replies. Too bad you're in SoCal, I'd buy you a few drinks if you were in the Bay Area!   So I took everything apart and applied a bit more solder to shifty looking joints. Then I went through every single part to make sure it...

    Update #2:   Hey Guys,   I have some good news! The amp is working 100% when I select the input to be the front 1/8" jack. However, when I select the rear inputs, I have the same problem as before, where the right channel is fine but the left channel you can barely hear. I had 2 327 ohm...

    Thanks Wotts! I have a hammond aluminum chassis. I know one of the pcb mounting holes is meant to be grounded. I have my pcb mounted to the chassis with washers and bolts on all the mounting holes. Doing a continuity test, all the mounting holes go back to ac ground. What is worrysome is that...

    Quote: Hey Wotts,   I didn't do the resistor mod described on Pete's website. I ordered a chassis 4 inches wider than the one he used, and spaced apart the output transformers from the main power transformer. I could try to do the mod tomorrow and see where it gets me. I wonder if I can...

    Quote: Thanks for the reply Rick!   I had swapped the tubes and it didn't make a difference. I originally thought the issue was with my 1/8" output jack and so I de-soldered it and replaced it with a new one. Now, not only do I have the same issues as before (can't really hear left...

    Hey Guys, Finally finished putting the amp together this weekend, after all the parts arrived. I am, however, having some issues. I would appreciate any suggestions for debugging the following issue: I have very little sound output from the left channel. It does not matter if I use 1/8" front or...

    Hey Guys,   Thank you Mr. Millett for creating such wonderful projects for us do to. Just bought all the parts, and I guess the transformers will arrive in 6-8 weeks. So excited, this is my first DIY project. I have a Computer Engineering degree, but nowhere close to that of a EE, so just a...

    How much did the WE396A cost you? I can't find a NOS for less than $50 per tube.

    Creative X-FI Titanium HD Optical Out.

    Hey Guys,   I am just curious as to if the Titanium HD uses the DAC for optical out or if it bypasses that stage since no analog conversion is necessary. Just wondering since my optical out is going to my Maverick Audio TubeMagic D1, and I am putting in the Burson discrete op amps in there...

    ATH M50 Expectations?

    I own a Pair of Sennheiser HD-595s (modded), ATH-M50S, and DT770 PRO-250. I have a modified Maverick Audio TubeMagic D1 (modified tube/op amps), along with Fiio E17.    All I can say is, I have no idea why people like the M50s that much. Sure, sound isn't that bad, but the sound stage can't...

    Vsonic GR06 Review

    Hey Civictyper16,   I use the GR06 sometimes on my Iphone 4S, without an amp, when I'm on the go. I also use it on my Laptop, which has an X-FI sound card by creative, a low end one.   I also sometimes use the GR06 on my desktop, which has a Creative X-FI Platinum sound card, with an I/O...

    Vsonic GR06 Review

    I just bought my pair of GR06 from lendmeurears.com, and i surprisingly love them. It cost me about $58 including shipping to California, and arrived in less than 5 days.   I claim to know nothing about IEMs, but I do have some knowledge in Amps and over-ear headphones. I own a pair of...
