Esoteric N-05 vs K-01

I recently traded in my K-01 for the N-05 dac/network player and the outcome has been most satisfying. The N-05 sports the new gen AK 4490 chip while the K-01 has the 4399 chip. With its usb input, the N-05 betters the K-01 spinning discs in its transport.

Found this link that may explain how the N-05 can sound better than the K-01 :-

Re: Esotetic N-05 vs K-01

Thanks, Mike.

Yes, apparently the app is designed by Lumin with the Esoteric name tacked on.

A forumer at CA has compared the Linn, Lumin and N-05 and he finds the N-05 giving the most balanced SQ of the 3.
The Lumin uses the Wolfson chip which is very well regarded too.

As the administrator, could you please edit the the thread title to Esoteric? Bugs the hell out of me. Haha!
 
Done.

The Lumin A1 (the original) uses the Wolfson DAC. The top of the line Lumin, the S1, uses the Sabre DAC chip.

Glad you're liking it. I would love to compare it to the S1.

Many thanks for the edit.

At MRSP$6500, I think it is a bargain considering the build and sound quality.

Yes, look forward to a comparison with the S1. The CA guy had the Lumin A1.

Nice! Keep us posted on how it breaks in. Does it use MiniMServer as well?

Yes it does. But I haven't gone on to the network yet as the router is way too far from my rig.

Am very, very happy with the usb input via the iFi/AMR USB 3.0. After more than 300 hours of break-in, it is settling in very nicely. I was a bit concerned at first about its SQ vs the K-01 as it "only" uses the chip of the K-05X.
But now, I am simply amazed by its superior abilities.
 
Update :-

I had the K-01 for about 3 years before recently acquiring the N-05 which now has about 350 hours of burn-in.

1. As I am quite familiar with the upconversion/filter settings of the K-01, I settled down to ORG upconversion and OFF filter for all redbook/hires PCM files after 200 hours of burn-in. With DSD files, I use DSDFilter OFF.

2. I am using Windows 10 and JRiver MC 19 with DSP off, DoP for DSD files and set to play from RAM.

3. I use a thumbdrive coupled to an AQ Jitterbug and ported to the PC, Oyaide Continental 5S(all silver) usb cable from PC to the iFi/AMR USB 3.0 which reclocks and regenerates the usb signal. The SQ via this route handily beats playing from the PC's internal hard disk.

4. From the iFi USB 3.0, a bihedral Gemini cable (from the same company) splits power from the audio signal before going to the N-05's usb input.

5. I have not hooked up the N-05 to the network as the router is too far away from my rig.

6. In comparison with the K-01 spinning discs in its transport, the SQ from the N-05 configured as above beats out the K-01 in every regard. This is a night and day difference and not subtle. This could be due to the new gen AK 4490 chip in the N-05 but its usb implementation, power supply and analog output stages may play important roles as well.

7. To me, moving from the K-01 to the N-05 is a massive upgrade for all formats - redbook/hires pcm/dsd. Good redbook can sound as good as hires.

8. There is more detail without any added glare or harshness, instruments are better fleshed out with a more solid bass foundation, highs are airier and more transparent while the overall result is much more musical than the K-01.

PS : Grandioso/K-01X/K-03 X share the AK 4495 chip which is one step up from the AK 4490 used in the N-05/K-05X/K-07X

The above observations apply only to my system and my ears. :)
 
Given the N-05 is basically a K-05x with streamer instead of transport, this is fairly high praise you give! I had found that the shift was about a level up, i.e. the K-07X sounded near the K-05 etc. I wonder if some of the improvement you're hearing is also due to the fact there are no moving parts, and the buffer stage/filtering in the N-05? Whatever it is, a bit of a bargain relatively speaking.

I agree it is indeed a bargain compared to my old K-01.

If I remember correctly, you tried the different PCM filters. From google I found that a number of users like the SDLY* filters for (different models of) Esoteric. Do you have any comments about those PCM filters? Thanks.

Could be the Kimber Silver is a bit hot with the K-01.....With a more neutral chip the sound is sure to change & be delivered differently.

I find the FIR1/SDLY1 filters blunt transients a bit too much for my system, the FIR1 more so than the SDLY1.

The FIR2/SDLY2 give better transients but then things became too lean. The other thing about these 2 filters is that while notes emerge from a very black background, there is this great void in between notes that makes music sound disjointed, unnatural - sort of like truncating the decay of notes.

I initially liked the SDLY filters but when I switched back to OFF, music sounds more right, the flow of music is more organic, fluid.

Hope this helps.

Certainly, this is possible. It all boils down to system synergy.
 
I would love to see the inside of the N-05 vs a Lumin T-1. Anyone have a picture? Wizard?

But no mention of preferred settings for upconversion and filters.

True.

It says (my translation):

- Using Audirvana software, USB sounds thicker. Network streaming sounds lighter (leaner?) with higher flexibility (?). Each has its pros.

- When used with G-02 the sound becomes more focused and smooth.
