Esoteric K-01X or K-03X??

Thanks for everybody's input!

Hi 68pete

If I’m correct, these new Esoteric CDP’s different multi settings (filters) and up sample rates is only for playing music file for CAS (Example: DSD)? Amy I correct?

However, my friend only use it to play audio CD and SACD, so it shouldn’t related to multi filters and up sample rates.

Hi dgarretson

I think even my friend just use it for less than 200 hours, the sound should not lack of musical and dry. So what I’m thinking is my friends’ equipment like amp, speaker and cable does not match with his K-01X.

And sorry I missed one information, this K-01X is not a 220V CDP  (My location is using 220 to 230V), which is a Japanese version 120V product. The seller convert it to 220V by setting the internal jumper, so I’m not sure if this will change the sound quality a lot??

Thanks! Seem like the up-sampling rates and filters are very interesting thing to try. May I know is that mean different up sampling rates and filters produce different sound character? For example:

Up Sample-1 = Very clear, very high analytical and transparency sound

Up Sample-2 = Rich, more thicker and transparency sound

Up Sample-3 = Between sample 1 & 2

Am I correct?

About the Stanford Research PERF-10 : 10 MHz rubidium audio clock. As I know many 10M rubidium Clock/ Oscillator need to work with an external master clock like Esoteric G-03X, G-02 or G-02. But according to dgarretson, it seem like Stanford Research PERF-10 can WORK with K-03X/ 01X directly and without necessary an external master clock, am I correct?

Just look at the Stanford Research PERF-10 information, it don’t have any setting of the frequency (Which mean to the tell the CDP what frequency to use: 44.1 kHz or 48 kHz”, so I think it still need an external master clock with work with it. Unfortunately I just sold my Esoteric G-03X……..This is another big investment to buy a G-02 and a Stanford Research PERF-10………

Because my friend’s K-01X don’t have any warranty service, but a brand new K-03X is include one year free warranty service.  And I can get t at around USD 7080 after negotiate, so finally I order K-03X and I will receive it this Thursday.

After I order my new CDP, I saw a pair of beautiful, excellent condition’s used walnut burl Avalon Opus Ceramique speaker in a 2nd hand audio shop. I always dreaming to own a pair of maple burl or walnut burl Indra for long time, but I cannot afford Indra. I’m also thinking to upgrade my Ascendant II if I can get a good condition Opus. So this is my destiny to meet this pair of speaker. Immediately I test it, I love the sound and then I use my Ascendant II, add some money to trade in this pair of Opus. A new CDP and a pair of speaker is a big investment for me, I got to be careful when using money in the near future….

Unfortunately, only one year warranty service in my region provided by the dealer. And this is one of the reason why the price is cheaper than normal market price.

I also tried original, 2Fx, 4fs and 8Fs in Up-conversion setting, but all sounds very similar to my ear (perhaps I have bad ears……), so I just pickup a combination that sound nice and more noticeable for me, which is:

Up-conversion = DSD

PCM = SDLY-1

DSDF = On

BTW, how can you choose 176.4kHz in 8Fs? It seem like you can’t choose the kHZ (?)
