That is what I have read from a lot of people, so I thought I should be good with communication but I honestly do not think I can use the Holiday as an excuse because it has been a couple weeks. I really hope it makes it trhrough china air just in an envelope... I get concerned with the pins and them not being in a little box or something, I am hoping it comes quick and safely, I know it is only 10 dollars but for me 10 dollars is an awful lot for me. Anyways It is okay because put the 2227 in my Cmoy bb that had the NE5532 and it sounded good really decent separation detail, impact, and more musicality than the OPA2134 without being as dark sounding, that is the best way I can describe the opa2134 is dark and thick like syrup if that makes any sense. I ended up putting the NE5532 in the M-stage for now and I do like the sonic differences quite a bit, I have a ne5532 in other portable the Gemini Doctor's GemTune Ws1.2 bluebird, Which sounds a lot better than the price I got it for.
I hope it works out at least.
That's what I find:
The OPA2134 is a bit dark sounding.
Your description of the NE5534 is similar to my opinion of the LM4562.
I haven't heard the NE5534 in the Matrix so I can't compare it to the LM4562 in the Matrix.
When I ordered my Matrix Quattro amp from Tam Audio, it took 12 days to get to Canada, shipping was free so I have no complaints, free shipping usually means slow shipping!
I also had an LM4562 in the order, the packaging was good.
