On the D1 I know it uses one slot for the DAC aspect, so you could slot in like audio-gd HDAM or something like that.

As the D2 has no headphone output or anyhting like that and I wanted to put the HDAM in, do i need to replace all 3 ? or just one for the tube pre-out?


I have a friend that wants to get a D2 as a D1 is not needed and wanted ot know if the upgrade path I followed can be done the same.
 
Thanks Spanky!

  any one used the tube magic d1 amp? my friend got this dac and the da 1 amp too, he got HD600 1st then the left driver had wierd sound later on, then bought HD650, and same happened later on, like less than 2 months if not one month
 
he asked around and turned out the power of the d1 is what caused this problem for him,  did anyone heard about similar issue with this amp?

Not that I am aware of but warranty should take care of it.

Maverick Audio TubeMagic D2 DAC: Upgrades and Mods
 

 
The journey to better digital sound started with the Maverick Audio TubeMagic D2 DAC.  Additional improvements to the sound can be obtained with modifications.
 
On the solid state side: the sound improvement of installing discrete component op amps is category changing. WOW.  
 
The other available “plug and play” socket is the tube. 
 
The gains upgrading the stock 6N3 tube with the GE 5760 is well worth the incremental costs.  Beyond “Tube rolling”, and inspired by the replacement of op amps with discrete circuits; I thus set out to replace the stock tube with an entirely new tube circuit, installing a cathode follower buffer tube module.
 
The improved sound was immediately recognizable compared to the previous internal GE 5760 tube-out. Also the sound was improved in comparison to the upgraded discrete component op amps, but more subtly so.
 
These upgrades, individually and/or together, notably improve the DAC to a much better performance.

The cost of the cathode follower tube buffer module upgrade is about $60 with parts.

I presume the 3 opamps are split for certain in and outs? or are they all active at the same time?

"The D2 requires 3 dual OP AMPS to operate.  All 3 must be swapped together per Ryan@Maverick Audio."
 
(Thank you to post #61 for this info)

I have a D1 which only uses 1 op amp (one for headphone out and one for the tube preamp/output) so on the D2 it uses 3 op amps. If I wanted to use the Audio-gd HDAM, I would need to get 3 for a D2 then correct?
 
I wonder how that would sound.

Yes, The D2 requires 3 dual OP AMPS to operate.  All 3 must be swapped together per Ryan@Maverick Audio.

Shroker, as you are already using an upgraded discrete op amp in your D1, you likely know this to be true.

Million miles different.

Very curious how having 3 on a D2 will sound haha.

What type of coaxial cable is to be used between the D2 and a CDP?  Best Buy and Radio Shack only have the thin pin type used for TV cable hook up.  Can you recommend a source and what to ask for?

Go to Amazon and search for digital coax.

always been happy with bluejeanscable.  Good quality, reasonable price.  No snake oil.

Are you able to run both sets of analog outputs in parallel on the D2 (or older versions)?

 

[dumpingground]

Both the solid state and tube outputs on the D2 are active at the same time.

yes

 

[satori1]

  yes

Thanks. Should I expect any signal degradation while using both the tube and solid state outputs at the same time? Perhaps a difference in levels?
