The pre-amp goes DAC-> Tube -> out.

Thanks Shroker! That was my impression but i wasnt sure.

Im setting up a first-time budget-yet-quality home headphones setup, with some good 2nd hand gear. I have an opportunity to get a cheap 2nd hand unit, which i'll connect to a corda concerto amp.

Intlsubband,

 

Shroker is correct,

There are the two analog output stages in the D2. There is a typical direct digital to analog output stage (labeled "Normal"), as well as a digital to analog by way of tube stage (labeled "Tube Pre Out"). Both stages can benefit from upgrades either through OpAmp or tubes.

 

These are directly from Maverick support pages:

 

"Carefully designed analog processing circuit - Without a good analog stage, even the best quality digital music will sound dry and lifeless. After all, music will only be played in analog format via amplifiers, speakers and headphones. We spent a great deal of time to enhance the analog circuit to make sure the analog signal will sound natural, transparent and full detail."

 

“TubeMagic” vacuum tube preamp outputs stage - The TubeMagic D2 comes with a vacuum tube pre-amp output stage in addition to the normal solid-state audio output. Powered by a vintage vacuum tube made in 1970’s, it adds a lot of warmth and smoothness to the music, especially to Vocal and Jazz genres. Furthermore, you can use this DAC as a full functional tube preamp, adding the “tube magic” to the four digital inputs."

 

I hope that answers your questions.

Instlsubband,

 

"Does the "normal" analog out represent the analog signal out of the DAC but not amped?"

 

Did not see this portion of your post.....the D2 is a DAC only unit, it has no amp output stage.

Thanks heaps VTHokie83, I am getting the D1 with the upgraded tube, 2nd hand from ebay. I realise that the D2 is a dedicated DAC, but will be using the D1 as mostly a DAC.

 

So yes, I did get my answer - connecting to the "normal" RCA out will use the D1 as a DAC only.

 

Another question that I have is whether I should try connecting my amp to the RCA tube out as well? or would this be double amping and bad for the SQ and possibly bad for my amp?

post #710 of 762

Intlsubband,

 

This will be "double pre-amping" on the D1 and I have no experience on this with either the D1 or D2. I might suggest sending an email to Maverick tech support to get a better answer to your question, I've found them very responsive and helpful with any question I've sent to them.

 

When I was using the D1 I used the internal headphone amp to drive Sennheiser HD558 and Graco SR80i headphones, and I connected either of the analog stages to a Bob Latino VTA ST-120 tube amp.....I found that the "normal" stage combined best with the Latino amp.

 

When I upgraded to my current configuration with the D2, I use the "normal" output to feed the Latino amp and the "tube pre out" to drive a Schiit Magni headphone amp.

Finally got a pair of HD650's! Can't wait to try them out with the D1.

Helpful...Thanks for sharing.

I'm considering D1 as my first DAC / headphone amp. Am I correct thinking that I could use the knob to control my active speaker's volume with basic model's knob, not with the plus version? Could I connect my KRK's to the tube out with rca-xlr or should I use the normal out?

 

Sorry for the dumb questions, I'm new with these things.

That's certainly not a dumb question. 

 

1. The unit is capable of controlling the volume out on any D1 model by the volume knob.

2. On the plus edition this is disabled because of concerns over sound quality degradation. You can easily enable it by taking the cover off and changing the pins on the inside to be variable volume control. This may seem a little bit overwhelming if you don't have experience, but it's really simple. 

3. The KRK could be connected to either output on the back of the unit (tube or 'normal').

Thank you for the ansvers :)

 

At another message board one D1+ user said that he didn't have to change anything inside the dac to make the volume knob work with his speakers. Guess I'll just find out what happens when I get the dac.

no problem. Also forgot to say, Welcome to Head-fi! There's lots of interests in here, so feel free to hop onto threads and post and ask questions. We're pretty nice people (well, not all of us). :p

 

Some people requested that the pins be switched by Ryan before he sends them their unit. If you're buying it from Maverick audio or a decently knowledgeable seller, they shouldn't have an issue swapping those pins.

Thanks for the warm welcoming, it's pretty uncommon in (at least in technology-oriented) internet forums. I had some problems with ground loop when I used rca, but connecting my KRKs with a 2 x xlr -> 3,5mm eliminated it. Does D1+ > rca > xlr have the same effect or should I just switch to rca > rca?

We're generally a good community. Sometimes we get a little fiesty on certain, hot topics, or debates. 

 

I'm not totally sure on that, because of your wires. The RCA and XLR are the same connection, but the XLR has an extra "shield" connector that prevents interference and feedback. It's possible that your RCA->XLR connector has that extra "shield" connected as well, which is why it eliminated the feedback your were getting. Either way, no harm in going RCA->XLR.

Guys, need your advice on my setup. My D1 (with opamps swap with LT1364CN8 and LM4562NA, and tube rolled with WE 396a) and i treat it as tube buffer between my CDP/DAC and integrated amp. There is no problem with integrated amp input set to tuner/line in, but if I change the amp input to CD in via the same RCA cable, the sound scatter and lack of bass, And if I connect directly from CDP/DAC to CD in of amp via the same RCA, the sound back to normal. So would it be that the tube rolling/opamps swapping somehow change the voltage of of tube amp out and the CD in cannot cope with it but line / tuner in able to accept it?

Burdie,

 

Unfortunately I have no experience with the setup of yours or problem that you are having. If I was to take a shot in the dark it would be the fact that the D1 uses "upsampling", and this is interfering with the data transmission. But as I said, I have no experience here. I would suggest contacting Ryan at Maverick audio, you can get to him either via the support website or by email.

I have found him to be incredibly helpful and generous with his time. Keep us informed as to the outcome please, it helps us all.
