Getting more and more impressed with FO 1.4, nice 🙂
And I only have them 10 hours playing.
I noticed that I hear more details, especially in the low mid compared to my F5.
With foobar on pause and volume on max my speakers are dead silent with my ears at 1cm from the drivers. Very deep black noisefloor 🙂

Low distortion and perfect grip will cause you to crank up the volume next, for sure...
You may want to try (and all that are stuck on Windows) the best (by far) player I've used:
Bug head
Scroll down for the free download link. It will take you a moment, though it is a bit tricky to understand at first, but believe me, it is worth every second invested. 😎
Good luck.

It has already happened 🙂Low distortion and perfect grip will cause you to crank up the volume next, for sure...
Thanks for the tip on Bug Head, it looks more like a DSP player.
BugHead Emperor and Infinity Blade SQ players have trillions of options for optimization, depending on PC/DAC environment. Here's thread for you:
Infinity Blade HQ (Bug Head Emperor) worth trying - Page 21 - Computer Audio - JPLAY - hi-end audio player for Windows
I am just happy to have it playing; won't spend hours choosing best parameters...or may be later...
It is amazing what this guy, Mr. Hiroyuki, is doing all alone and for free... 😱

After plugging in and out all the Wires a lot lately,I cleaned all the Contacts last Night with
Gold Contact Spray and I can tell You everything got even better .More natural and refined.
I can only say try it !!!

That's what I got, surprised too. Maybe this is Samwha's genuine producer. 😀Su'scon and "SK" electrolytics? Hypex changed suppliers? Now chinese electrolytics???
If you give me an idea for better SMPS, I'll try and compare. Mind you this sucker gives 60V/15 A on 4 Ohm load, violently arching when disconneting. 😀
Got my second SMPS 1200A400 yesterday and it got those new Caps too.Too bad they forgot my Cable Kit, would have been nice testing on Weekend.

Signal to noise ratio
> -110 dB
So it is, dead quiet. PSRR is in the same range, clever circuit enabling use of unregulated SMPS or conventional PSU, no mains frequency present in the spectrum and all that with just two electrolytic capacitors present on the PCB. Also very future friendly when recapping will be needed.

Cant wait any more! 😉
Cresnet,did you buy the new FO 1.4 modules?
Yes I did, and will enjoy them soon. 😉
Installed second SMPS Yesterday and LC is right ,it is ok with one,but now Imaging,Separation is better and it is like Musik is getting away from the Speaker. I like it.And another Thing is,it is dead Quit now.

OK. If it weren't for the dirty $$...
Another adverse effect that I found is that I am now listening more symphonic music (XXth c.) and less chamber music 🙁 profiting from the total command the F.O. offers...

All present here can finally believe me, just copy paste what I show and preach all along this thread and you'll get a real music at your home.

Another Black Mamba hit the road

Hum - Need input on wiring
I completed the First One chassis and wiring, confirmed the settings, and connected inputs and speakers. It is a two channel amp running on +/- 55VDC from a linear supply as shown. Sounds great except for a low level hum coming through the speakers that does not vary with volume. The hum only occurs when BOTH inputs are connected. I have tried two sources (MiniDSP 4x10 and Samsung S5) and both result in the same hum. If I disconnect the left or right input, the hum disappears completely.
My wiring diagram is attached. I have shown one channel, but they are both wired the same way. The only electrical connection to the chassis is the earth from the mains wiring.
Any suggestions?
