REDDI Tube DI Mega Thread . Potential megathread that is.

OK, not sure if I did this right, but since I got two different results, I'd like to think I did. Tried the BlueCat program with much better results. Took a white noise sample I found online, pasted it into the DAW, ran BlueCat on it, and here's what I got:

EDIT: Took this down because there was something not right about my tests and didn't want to put out inaccurate info.

Thanks, Jimmy! This isn't quite what I expected to see, and the results differ enough that I'm wondering if there is something else going on there. Getting a good scope of something can be a bit challenging. I expected to see more of a bump in the lows and low mids myself, but it's been quite a while since I used a REDDI.
 
#923
I've always heard it as relatively flat personally. I did expect a little more grunt on the bottom with the NOS tube but not to a silly level or anything. Could be wrong, though. And I could have easily done something messed up with these graphs, no doubt. I'll have to double check my work. Also I might try feeding the white noise signal through the MP3 player and into the computer instead of laying the raw file in the DAW. Maybe that could have skewed the results...
 
#924
Yeah, I wouldn't expect a huge bump. Maybe 2-3db max in 150-250 hz range, combined with a slight drop off of about 1db per octave starting around 1khz is what I was thinking. I hear the REDDI as being mostly flat, but with a relaxed top that has a sweetness to it, along with some warmth in the body of the voice where most instruments sit. Definitely not what I'd call round or old school, but warm in the middle with the highs and lows there just to fill out the tone. It's been so long for me though that I could be wrong.

Well I just tried doing the white noise from my MP3 player into the computer directly, and there was enough of a discrepancy between the original file being laid directly into the DAW and the MP3 being played through my cheap player, plus enough similarities to the REDDI graph and the new graph, to declare my graphs to be BS, so I took them down. Obviously I have to figure out another way to do this.

Good call, Jimmy. I had to do the same thing a year or so ago when the GB Streamliner came out. I posted some graphs, then upon digging further and talking with agedhorse offline found out a few things I had done wrong which made the graphs totally useless, so I yanked them to prevent spreading misinformation.

Tru dat! But I've lost interest in scoping it out now. This was a lot of work only to get it wrong, and it really doesn't matter what it scopes out to me since I end up EQing anyway. The un-EQ'd sound is awesome, but I like my 5k rolloff and a bottom end similar to my 810.

I'm in! My new Reddi just arrived last night.

Jimmy,

Lots of work and thank you for the attempt.

I wish I was watching this thread more cause I would have saved you some time and trouble.

I have 3 outside houses that spec all our gear before we release them.
The reason I do this is I don't want anyone to say we spiked the results.

Now here's the thing with having 3 independent houses doing this.

I received all 3 reports and NONE of them are 100% the same. They all have different results but we are not talking night and day differences.
So what I have to do is take an average and then post the results. I do however test ourselves and compare to theirs as well.

Now all the units sound the same but with different results and this is normal in most cases (even when we give them the procedures to test with). The differences can be anywhere from the scopes/wires/connections/ etc that will cause this to happen.
The same testing with the same outside houses will yield the same results each time or maybe a slight difference due to outside influences during testing.

Now here is something I found out a long time ago.
I have a product (Tube) that when we place it on the bench the specs will drive you out of the room. They are the worlds worse :rolleyes:

But when I or ANYONE plugs a mic or bass/guitar into it ..........it is the sweetest sounding unit on earth (IMO).

So bottom line is no matter what the readings are on a piece of gear does not mean that it will sound bad OR good for that matter.

Now if someone here wants to scope the REDDI contact me and I'll see what I can do to help.
BUT before you contact me I will ask how qualified you are and your experience doing bench testing and the equipment you have.

Thanks again Jimmy for doing all that.

Thank you for the reply, Peter. Will reply in more depth later tonight. Have to head to a lunchtime gig right now, but just wanted to acknowledge your reply before I left. Have a great Sunday!

After a few days of home recording use with the Reddi and the other DI boxes I have, my conclusion is simple: To me, the Reddi has the warmth of the SVTDI and the clarity of the DB900. The best features of both, + a level knob.
I think the Reddi is excellent. I'm looking forward to bringing it to the studio soon. :bassist:

Thank you DJJazzV,:hyper:

I think once you get into the studio and track you will be a happy camper.
The one unexpected thing that will make the Engineer VERY happy will be, not JUST how it will sound but how well it will sit in the mix, making HIS job a whole lot easier. :D

Thanks again not only for the purchase but for your input as well.

Best,

Yep, all that really matters is how it sounds. I'm with you on that...I was a little curious about how it scopes, but it really doesn't matter for one, and looking at a straight up frequency graph won't tell you all the little nuances like how uncompressed it sounds and feels to play through, or how sweet and natural the top end is, things like that. I will readily agree with you that specs are one small part of the story for the player and by far not the important thing.

And I have seen the same gear scope out different ways for different people on here as well. Like you said, not a drastic difference, but enough to cause an argument ;) Which leads to another important point...not everyone is good at interpreting data. People see data and think it's cut and dried and it isn't. Saw this with a cab scope just recently...the guy was using a 3015, which according to Eminence has a spike at around 1.5k, and the result he got with his cab mic'ed and on a scope was the spike being smoothed out. I guess maybe if someone else scoped it, they could get that spike back if something changed in the testing process, too.

So I get your point. Thanks pal...have a good week!
