post #736 of 751

I have a question about the E7 and E9...

I own the E7/E9 combo which Ive been using for the past several months and have served me pretty well, but I think i'm ready for an upgrade. I'm pretty sure that I can do better with the E7 considering the DAC component, but I want to know whether I need to replace the E9 with another amp in order to get better sound quality, or whether it will pair well with a DAC like the HRT Streamer, AudioEngine D1 or U-DAC. Is it true that the E9 has a subpar audio component that adversely affects sound quality? And what would be a good DAC/amp to upgrade to from the E7/E9 combo? Thanks.

 

Edit: and by the way, if it matters any, I will be using the dac/amp with the SRH-940, Sennheiser HD 598 and Audio Technica M50.

Would it be possible to use e9 to power passive speakers?
I know it is not designed to do so, but maybe there is a way around?

I just got my e17 and i was hoping i can make a pc fi
Desktop system for 2 bookshelf speakers i have.

It would work to some extent, but not particularly well. It would lack power, the sound quality would not be good (the output impedance is too high for speakers, for example), and in the worst case the E9 may even get damaged by driving 4 or 8 Ohm speakers at high levels.

Thanks 

I guess it is not possible than. I just thought there was an efficient way to spend my money with out buying things twice ;)

Sell FiiO E9 and buy some good and simple DIY rather than another chinese mass product.

Even after modification and swapping of many op-amps, my friend again starts to complain about irritating sound signature of E9, and summary medicore SQ and low SPL.

He has AKG K702, K280, Philips SHP9000, and compares FiiO E9 to quite decent (but not perfect) A-class DIY JFET/MOSFET amplifier. He try to pair E9 with FiiO E7 (WM8740), AK4393 DAC, 4xTDA1543 DAC, AK4396 soundcard, and two 4xPCM63 CD players.

low SPL should not be problem on the e9. It powers T1s without a hiccup so k702 should not be a problem on high gain (use that gain switch dammit)

I mean the Sound Pleasure Level, not a Sound Pressure Level - sorry for this ambiguity. I simply can't stand "technical" sound of FiiO E9 on any DAC/CD, album from my collection and any headphones.

Beyerdynamic T1 is 600 ohm and very effective, so it's easy to drive even with the voltage gain 1 of the amplifier, but AKG K702 is 62 ohm and voltage gain is also not a problem, but K702 requires more juice (more powerful output stage with giving more current), but again it is also not a big deal for FiiO E9 in the mean of technical correctness. FiiO E9 just sounds bad.

I don't really know how ruler flat sounds bad. maybe its irritating because its not smoothing over the k702 peakiness that no one wants to admit.

post #744 of 751

Does anyone know how it would compare to the little dot mk2? And Before people come up with bargain bin comments that tubes are better because they say so, i'd love to see just an objective comparison.

It has nothing to do with K702. FiiO E9 maybe has a flat characteristic, but add a lot of hard to measure intermodulation distortion, and sounds really bad.

Comparing FiiO E9 to any tube amp will be quite easy and FiiO E9 is 100% looser.

Jesus, borizm. Talk about objectivity and backed up arguments. Oh wait. 

post #747 of 751

At least spell loser correctly borizm. And if intermodulation distortion is hard to measure, why not measure it. its hard, but not impossible, and where do you get this intermodulation distortion from?

 

Have you tried it on a ruler flat amp other than the e9? And you said the exact opposite of what i asked,would it seriously be worse than the indeed hybrid mini amp, Bravo V1, or any other cheap chinese tube amp? 

 

Be objective and don't just rattle off lower priced items because you have a huge collection of mid fi and high end stuff that you are probably biased to. Also, compare it to something i can find and see with my own two eyes. Otherwise your magical breeze audio e4 is like a bucket thats been hit by a shotgun, and the only information i could find on the breeze was a picture of it with an exposed pcb plugged into some stuff, and i am not completely sure it is even the right amp I was looking at.

 

And if your breeze is so great, hook me up with a site to buy it and a price.

I have bought the Breeze E4 kit some times ago - I'm trying to find where.

Breeze E4 has been sold also as a ready to use product [in enclosure], but probably not any longer. Breeze E4 sounds very good, but requires a few minor changes to sounds better.

I'm in middle of creating my own, much more simplified, better designed, smaller, and sonically even better headphone amplifiers, first: pure symmetrical and JFET/MOSFET only, A-class design, and second: similar but fully balanced [2 times more complex] - both easily able to drive HiFiMAN HE-6 very loud. I'm building a early prototype, and is very promising. Probably I will be selling it as a kit or assembled without enclosure world wide or only for my friends. I let you know - it's my hobby only, so patience is required.

is the e7 and e9 combo for 170 better or audioengine d1 better for the same price
