The K9, in simple terms sounds thick and syrupy, with a mid bass prominence, where the SU9 Pro and L70 is so much more transparent - with the HiFiMan HE6se it is almost microscopic detail level (still shocking me!) - even redbook sounds new and fresh. Neither are a bassheads dream, you’d be...

I can, but before I delve into that, are we just talking about the DAC section of the K9, or are you looking at K9 vs SU9 Pro & Topping L70?

I swerved at the last minute, and instead of getting the Topping E70v - I went with the SMSL SU-9 Pro to partner with the Topping L70 - glad that I did, the combination is glorious - add in the full velour pads that I have gone with, the HE6se sounds incredible... I know there is talk of DACs...

I've just got the SU9 Pro today, partnered with the Topping L70- a bit disjointed from a 'stack aesthetic' perspective, but - the difference between the SU9 Pro, and the LO output of the FiiO K9 ESS (ES9068AS) that I have been using is crazy - it has quite literally brought the L70 to life (not...

Sounds good to me, better than the K9 I’m taking it you’ve had QC issues with their products?

My guess would be that you have the headphone port in LO (line out) rather than PO mode - if so, change it and you’ll get your volume control back.

I bought a Topping L70 amp which is definitely cleaner sounding than the FiiO K9’s THX amplification (sounds thick, bloated and muddy in comparison) - I’m very happy with the K9 now being reduced to DAC only duty - as many before me have mused - the HE6 family are very compelling… definitely the...

I’m starting to think that the FiiO K9 (ESS non pro) is enough… there is only one track that I’ve heard that they really clip on if driving the amp hard - otherwise to me they sound glorious - I think it’ll be a bit of a blind punt to get another amp (have been looking at the Topping A70 Pro or...

I believe this to be borne from the HE6 (and it's sub variants) being very inefficient - I have the HE6se V2 and a FiiO K9 (2w per channel at 32ohms) and I can hear, the higher up the volume dial I go that the bass becomes crunchier (distortion level noticeably increasing) which definitely does...

So, straight out of the box it is a bit love / hate, I love the SQ, but the K9 just doesn’t have the oomph to make them shine, so the upgrade part continues… Edit: if I stick within the volume capacity of the K9 amp, the HE6se sound phenomenal, totally smitten with the SQ / $~£ value - I’m...

I’ve just ordered a pair of the V2 to be delivered tomorrow… I’m a bit confused between voltage and wattage - currently have a FiiO K9, which I think is undernourished at 2W output at 32ohm, but the last spec: Peak output voltage ＞42Vp-p Makes me think it should have enough drive? Does...

I've been down this rabbit hole for a couple of days now, I bought an Amazon Warehouse Oyaide D+ class A A-B cable after reading and watching some reviews, it is the last little itch that I want to scratch for now, anyway - it turned up, and - someone had done the dirty, swapping the proper...

That’s the only one, yes (other that the one that turns the RGB back on again).

It’s funny, I hate two pin because I like the freedom of movement for best fit - ironically, it is only the FH7 that have had a bad MMCX experience for me.

Yes, but it comes back on when you power cycle… it does for me anyway. I’m on 1.31fw, so I’m not sure what’s up with that…. Anyhow, sorry, I’m OT - hopefully the user who was having issues with the K7 has resolved them now.

What AV are you using? I had no problems… I wish I could permanently disable the RGB on my K9 how I could on the K7

Balanced, Sundara Closed (20ohm)

Random question, and sorry if this is a case of RTFM - if listening to a particularly bass heavy track at quite a high volume, I get a red ring of death (released by muting and releasing the mute) is that caused by me exceeding the max output power?

I’m not really a metal person, but they sound great to me on Leo’s covers (Leap Frog Studios on YouTube). I find them genuinely excellent for movies as well… whether that be a magical combination with the K9 amp or just that they “work” I don’t know, but for the price they’re at now, simply...

Maybe I’m a mid-fi person, I find them great, although they crave power, the sub bass comes out in spades if you push them…. A particularly sub bass heavy track that I like gets the drivers really flexing, albeit that my FiiO K9 goes into protection mode if I get silly and push them hard… that’s...

My tip of the month with the FD7 is the Tangzu Sancai - very open, with a tight bottom end, worth the price of entry even at the surprise inflated U.K. prices.

I think - based on this review that I have the best of both worlds then with the K9 ESS and K7 & PL50 PSU, this quenches my potential annoyance of backing the wrong horse :) Edit: another way I’m covered is with the M11 Plus LTD - balanced line out into the K9 ESS, thank you for neutering my FOMO.

As a matter of interest, what volume do you listen at, and - as a sub-question, does the clipping diminish / vanish if the volume is lowered?

The orange extra cable in the box is what you use for the M11 to be the “transport” then get a coax digital cable (to make sure it is the correct ohmage) and you’re set… then you can decide for yourself.
