I wonder, this question especially to T.IIZUKA and PALCHIU but of course others can pipe in, do the mods you installed improve the matrix's imaging? If so, then those blue and black label matrix editions may be a real winner.

I'm enjoying the process. 

 
 
Modifications not recommended for everyone.
I have done that with knowledge of risk.
 
Will buy yen were JPY70,000(about $840) ONKYO DAC-1000.
I do not see mod.
 
Advantage of MATRIX mini-i think its high cost performance.
The multi-input is impressive.
And the fun modding.

mini-i If the remote control operation, it is better.

In other words, you enjoy to mod.
 
When I do it, it will be to mod to enjoy

2xPCM1795 for each channel!
 
USB accept 192k input, and can upsampling!

There's a review here comparing the XDA-1 to the Matrix;
 
http://www.head-fi.org/forum/thread/528635/emotiva-xda-1-vs-matrix-mini-i
 
Apparently the matrix wins on sound quality and the emotiva wins at imaging (detail, location of instruments, width of soundstage).

XDA-1 get bigger power and better output stage, but after little mod. it's really improved.(detail, location of instruments, width of soundstage)
 
Because I need compact size, I choose Mini-i w/mod it.

I noticed that when you guys substitute opamps in your matrix, you tend to "keep it the family" so to speak. You switch from a OP275 to an OP675 etc. Why not try something like the LM4562NA? It seems to be a well regarded modern opamp.
 
 
I had the LM4562NA in my Beresford TC-7520 and an OPA2132 opamp. They were different but both were nice too. They were my 2 favorites of the 5 or 6 opamps I had tried in that DAC. The LM4562 took a long time to settle down, though. Like 3 weeks. Once it did it was great.

Wow, that looks really sexy. I wonder how much it'll cost.

 

[Hellenback]

Parts seem pretty high end "tried and true" and it likely sounds very good. x2 on what it costs?

 

[akhila]

This might be the price of Matrix 100plus
http://item.taobao.com/item.htm?id=6105957960
 
approximately $300.  Quite reasonable at the cost of Matris mini-i nimus headphone amp, which could mean a better DAC parts and sound.

I started to salivate and then realized: no volume control on the 100plus

With my mini I i got rid of the pre-amp and I have no plans to go back.

hey guys.  what's the best place to pick one of the Mini I's up if you live in the US?  also, what voltage should I go with?  I'm not sure what the difference is between the 2 options.  thanks.

I'd say coolfungadget's regular (non-eBay) site for the best price, and he's a reputable seller and member on HeadFi. Your voltage should probably be 110 if you're planning on using a typical (US) household outlet.

 

[ajreynol]

awesome, thanks.
 
now I just have to decide if I want to go with the Matrix or the Burson 160D.
 
good problem to have.

Finished replacing the capacitor. 

 

 
 
This is the end of the capacitor replacement.
TPA6120 coupling capacitor is the default state.
HPA does not use it as a replacement.
 
 
 
DAC (AD1955) for capacitors, Sanyo SEPC was changed.
http://edc.sanyo.com/pdf/e054.pdf
 
Sanyo SEPC 16V470uF x2
 

 

 
DIR for capacitors, Nichicon HZ was changed.
http://www.nichicon.co.jp/english/products/pdf/e-hz.pdf
 
Nichicon HZ 16V1800uF + WIMA MKS2 63V 0.1uF  x3
