Esoteric K01: What are the best settings for CD?


The Esoteric K01 has several up-conversion and filter options for CD play-back. Unfortunately, each up-conversion option and each filter option requires approximately 500 hours of 'break-in' to sound it's best. I have owned the Esoteric K01 since it's release. It is a superb SACD and CD player. I have 'broken in' some but not all filter and up-conversion settings. I am still unable to decide which combination I like best. I am currently using S_DLY1 (for digital filter) and 2Fs (for up conversion). I would like to know what settings other Esoteric K01 owners like best. It would be helpful if If you can explain why those settings sound better to you than other combinations. I wonder which settings the experts at Esoteric/Teac would recommend?

Hi Guido,

I have reviewed many of your previous comments regarding the K01and your wonderful review of the K01. I am now using a break-in disc with settings on 4X up sampling and slow delay 2 filter. I am amazed that you have had the time and discipline to break in all of the combinations and analyze the differences in such detail.

I do agree with all of your comments above.

What power cords have you tried with the K01?
Which power cord do you like best and why?
I currently use the K01 on a dedicated line with the stock power cord.

I read in one of your recent responses that you had the K01 for nine months. I am curious, why did you get rid of it?
What are you using for your front end now?

Thank you for your very thoughtful and intelligent analysis.

Best,
Matjet

One additional comment:

My K01 always sounds terrific, at all times. But, I have found that the K01 sounds even sweeter smoother, more alive with better harmonics, detail, transients, dynamics, sound staging and imaging (on all settings) after it has run for a few days non-stop. My amps, Krell 600e mono blocks, are also kept on while breaking-in the K01. The extensive warm-up apparently makes a significant difference.

By the way, I use a Kimber Cable balanced connection 1 meter KS1136 (Kimbrer's top of the line silver) connected to a Krell 707 processor in straight pre-amp mode. All pre-amp to amp connections are MMF CAST.

What are your thoughts on how much warm up time is required to reach peak performance?

Thanks again,
MATJET
Hi Guido,

I received your email, the information is extremely helpful. I am not sure if my response reached you so I am adding a comment to the thread, hopefully you will see it.

I am using dedicated lines for my amps (Krell 600e mono blocks), processor/pre-amp (Krell 707), and the Esoteric K01. I use 240v lines for the amps, 120v for everything else. I am using stock power cords for all of my equipment. I do not use a power conditioner.

I have no problems with radio interference or hum. The equipment is extremely quiet and music emerges out of a dead silent 'black background'.

Please explain how the Shunyata King Cobra CS cable would improve the sound. Also, how would a Shunyata Triton improve my system? Adding 4 King Cobra CS power cables and a Triton is a significant expense; is it worth the cost?

Krell warns not to run their big amps through power conditioners. Also, their amps can operate with 120v lines, but the company strongly recommends 240 lines for their big amps. Therefore I would probably use the Triton for the K01, Krell 707, tuner, turntable, etc., not the amps.

Apparently, the King Cobra CS is discontinued, replaced by the Anaconda Zitron. I may be able to get the King Cobra CS for $1750 (approx. 50% off). The Anaconda Zitron retails for $2995. Any thoughts on performance of these two products? Is the Anaconda Zitron worth the additional cost?

Thanks again for your help.

PERSPECTIVE: I owned the Esoteric X01D2 for several years before replacing it with the K01. I owned a Krell cd/sacd player (top of the line, I can't remember which model) prior to the X01D2. The X01D2 sounds much better than the Krell right out of the box, there is no comparison. The K01 sounds much better than the X01D2 on all settings, right out of the box, without warm up. The improvement is very obvious, A-B comparison is not required to appreciate how much better the K01 is than the X01D2. The Esoteric K01 is the best cd/sacd player I have ever heard, regardless of settings, warm-up and break-in. This is a fantastic cd/sacd player. The differences between each setting, break-in and warm-up improvement is subtle compared to the improvement over the X01D2.
I am absolutely delighted with the sound, build quality and operation of this beautiful machine.
Audiolabyrinth,
The break-in and settings are tweaks. This is a great sounding player in any setting. It sounds great without warm up, but improves with warm up. I'm sure your amps improve with warm up as well.

You guys are correct, the K01 sounds great even without break-in. On the other hand, it is built like a tank, it would be pretty tough to wear it out.
