Busman2 UA5 mod - demo
« on: July 10, 2005, 05:54:40 PM »
Well I gave the Busman2 UA5 op amp upgrade a run on Friday night.  Taped The Duo - outside and a Grateful Dead cover band at a bar - inside.  I was very pleased with the results.  Very clean sounding.  Not as noisy as the stock UA5.  And very transparent.  Before I bought it off Chris, I downloaded his sample of the OAD T-mod Plus and his mod.  I could barely tell the difference.  After using the BM2 mod, I can't be any happier with my rig than I am now.  +T and nice work Chris.

Below is a torrent which gives you a demo of Busman2's work, leegeddy's Bumblebees, and the AKG 414-XLS.  The demo is from the Grateful Dead cover band - Dark Hollow, from the Syracuse NY area.  I would have made a smaller samplel, but the band did a nice job on Eyes of the World.  So I thought I'd plug the band too.   ;D

oh ok, i find it funny that people have to mod something to make it work better.  why didn't the makers of the UA5 think before they made it.  THat is why I like apogee and grace.  they know what they are doing, no mods needed

Spyder, you couldn't tell a difference between busman's samples?  I listened to those 'Althea' sample and tho it wasn't huge difference, the bass was definitely looser with the busman's mod.  The highs were a little exaggerated, at least the ride of the cymbals were more 'sustained' and washed out.  Mind you, from what I remember of my old stock UA-5, a big improvment....but not in the same league as the Oade T+ mod.  FYI, Oade is NOT using the Burr Brown OPA 2134 chip, as Doug has said himself. 

A fine score, none the less.  If I wasn't nickel and diming busman, I would have probably been running that myself by now.

stock ua-5 = $275
v3 = $1300

there's a reason why the ua-5 is so much cheaper than a v3, they had to cut corners to keep the price down.  nice thing is spend a few hundred bucks on getting it mod'd and it can sound damn close to a v3 for less than half the price!  sounds like a good reason to mod it to me ;)

While the MiniMe and V3 are outstanding units, they retail for 5x more than a straight out of the box UA5. You pay for what you get. I don't think Edirol ever intended the UA5 to be a high end preamp/AD. They definitely did not intend for it to be used without a computer attached, and as an entry level consumer home studio unit, it seems to be extremely well thought out for $250. In fact, I'd say that on a cost vs. performance and feature set, even the stock units outvalue the Grace and Apogee units.

I don't think anyone can say that the first revision MiniMe's were perfectly well thought out - now the V3 is a different story.

Regarding Busman2, I think it is pretty cool that someone would offer to put the work and parts into trying to improve the op amps and sell it for negligible profit - esp since Doug Oade won't do it anymore.

+Ts to you guys and Busman2.

EDIT: I type too slow and Justin said it better faster than I did.

   Spyder9 Thanks for posting this and thanks for buying this and getting the word out there are other people who can help mod the UA5 now that Doug isn't doing them. I'm not trying to nock the V3  it is awesome and if I was rich I'd have one too more than likely, but I'm not and I like to try things out to better equipment for the fun of it. This unit is a significant improvement over the stock UA5. After listening to the sample I like it even more it is crisp in the high end with good response throughout the frequency range I also like the quickness of response for the bass it is nice and tight to me. It is what it is and it didn't cost $1300. I wish I had a V3 to compare it to just to see if it can hold its own.
   Johnw and Justin your comments are exactly why I decided to try the mods. In the end it all comes down to the almighty $.

+T to all of you guys for putiing your 2 cents in and I will be offering this service to other tapers here that might want it. pm me if you want to discuss it.
 No one said this is the Tmod just like the Oade mod I don't want people to think  that, it is only a different spin on the great idea Doug Oade put forth in modifying things to make them better. I am only a fellow taper trying to help myself and others have decent equipment to pull the best tapes our money will allow.

A fine score, none the less.  If I wasn't nickel and diming busman, I would have probably been running that myself by now.

Never said it was in the same league as the Oade.  No sir, that never left my finger tips.   But seriously, I couldn't really tell the difference.  Squinting just makes me dizzy.  I set up both tracks, one in Adobe Audition and one in Total Recorder.  Kept going back and forth, it was really close as far as I was concerned.  I even zoomed in on both tracks w/ Adobe, looking for any noise that would deviate the wav length.  Not much at all, if any.  Bottom line, its a big improvement over the stock UA5.  And its only the transparency mod upgrade.  Warm mods and presence mods are not available right now as far as I know.  Chris did a extremely nice job on this preamp and he should be commended.

Doug only supports those UA5's he modded.  The UA5 is no longer in production, so Doug won't upgrade any off-the street UA5s.  Since people have fallen in love w/ their Oade and are keeping them, some of us on the outside, who can't afford a V3, must make do.  Also, just because Doug is not using the Burr Brown OPA 2134 chip, doesn't mean that its an inferior chip to his.  Doug has not released, publicly, what chip he is using.  So we don't know what he's using or whether he ever considered this chip.  We don't even know what exact parts he used for the PLUS mod stuff.  At least I don't, maybe someone here knows more and wants to share.  We may never know with the way technology is changing in our field.  Either way, Doug is also commended for making a sweet upgrade to this box.  Excellent job Doug, with great sincerity!

I'd love to shell out $1300 for the V3.  But $300 I spent for the Busman2 UA5, matched with the 414-XLS and the Bumblebees, I think I can get some good sound quality out too.  Of course, one still has to consider: mic location and technique, sound quality of the stacks/monitors, the SBD mix, the room, drunken ass-clowns, and whether the band is "On".  I could be running $20,000 worth of equipment, and if any of these things become a bad factor, I might not have a good recording or a good time at the show for that matter.

So if we were to send you our UA5 along with the chip that Doug uses would you mod it using that chip.  There is a post here on TS that tell what chip he uses, and was allowed to be posted by Doug himself, so I dont think he would mind.  Just curious

Sure if you want to do that I can. I was told he would not release info on what chip he uses so if you know please post it here I looked on his board and this one and can't find it.

The chip he uses has been updated and the aforementioned one is no longer in production.  Switching opamps will help, switching out the caps in the power supply and analog outputs is where the unit will start to really break through.

it is called details, grace takes the time and research and pays attention to the minute details
while unlike edirol, they are out to market to the mass.
You pay for those details. The mods allow one to bring the unit closer to the big boys
who do pay attention to the details such as op amps and signal paths
