Glad you are satisfied, mine after 52 days was cleared by customs without tax, already sent to my state ...
With all due respect, but this file does not seem to me to be reliable.
why? this is standart test file with inverted phase! if you want to fool yourself it's your decision! the fact is it's more or less audible, depending on music
Screenshot your test results. I want to believe you, but without evidence it all just blabla from your side. Even though you can still easily fake these results....but whatever.
i read the conclusion, if you don't hear it it doesn't go away, and if we talk about bit-perfect sound, audiophile quality and do all the measurements so i don't know what's your point? as for me this is a very serious issue! and by the way a lot of people hear the difference on real music, instruments and setups, becasue difference is right under your nose (ears)
To give Topping credit, they admitted that it was an error and they are fixing it in already sold E30s by issuing a firmware update for the USB input. Future batches of the E30 will have all inputs featuring correct absolute polarity. The only issue that remains is the fact that they won't be able to fix the Toslink and Coax inputs on already made batches of the E30 without the owners shipping the unit back to them. One thing that they should have done is recall all the incorrectly wired units from the market until the issue was fixed. That or offer them at a huge discount.
but they didn't recall it! i ordered my device 10 days ago and they already knew about this issue for about a week or two i think! and they continued selling! that is what pisses me off
I know. If I was them, I would offer to fix the units in the field for customers and pay for the shipping back to China. Or offer a discount for the owner to keep the unit as is. Obviously this will cost them money, but in my mind, the reputation of their customer service is at stake here. I am very pleased that Topping have a very active and knowledgeable representation here and I really like their products. I have never had to deal with their customer service and I am looking forward to seeing how they will handle this. I know that they had some problems with their DX3 Pro V1 headphone amp stages - not sure if owners had to pay for shipping those defective units back. The situation with the E30 is more of an obvious design error (a small one), so it should be a no brainer.
It's definitely easy to identify the difference in that sample. It's quite obvious.
Preamp mode is good, sounds good with my active JBL 308 speakers, that's how I use it.
I would think it's better to control volume directly on the DAC via remote rather than turning down volume in software on the PC. So I would run it in preamp mode to allow for volume control at the DAC. Ideally you have maximum signal coming from the DAC to your speakers and then you control volume on your active speakers, but that's a pain to do, so in reality it's better to set a sensible volume on the back of the speakers and then use the DAC to control the volume.....you'd set the dial on the back of the speakers for the maximum listening volume you would ever want when the DAC is outputting a full signal (0dB), then you use the DAC to control the volume from then on.
hilarious? it's absolutely normal, because we found out about this issue right after we ordered it! it's a shame, don't you think so? and then we found out, that Topping already knew about it! while those who ordered it several months ago just accepted it, not such a shame
