    SOtM sNH-10G Network Switches x2 : The NEW KING of USB/Network Gadget Setup

    Hello valicu2000, if you look from the top of the SOtM sNH-10G you can see a green LED light blinking inside in one second rhythm. With a correctly connected 10 MHz external clock a additional second green LED light starts left of the blinking light to shine steady. The problem with the Mutec...

    Adjusting screw tightness on Esoteric K1X helps a lot!

    Hello Notdead, yes, you have to take out the pcb and replace the smd opamp with a Muses 03 four times in total. Be sure before soldering the opamp that the orientation is correct. Attention: if the pcb fixing screws are all out, you can easily pull with no force the connector to the side. The...

    Melco HA-N1Z / 2EX-H50 Digital Music Server - Owner Review (Part1)

    Thank you Kimurastanley for your hint to the new N10/2 with his additional linear power supply. Seems to be a real progress to the N1Z with the integrated two switching power supplys. There is a rewiev in hifistatement with pretty pictures: www.hifistatement.net/tests/item/3349

    Adjusting screw tightness on Esoteric K1X helps a lot!

    Hello AMR / iFi audio, It is a two stage 12 dB Filter with 1.8kOhm and 470 pF followed by 5.6kOhm with 100 pF, Feedback resistor is 2,4kOhm, so the gain is a little over 1, perfect for OPA627. Im sorry, Im not engaged in physical theory of OP amps and dont know much about it. So I depend on...

    Adjusting screw tightness on Esoteric K1X helps a lot!

    Hi! Fine to meet someone who is also heavily engaged in audiophile parts. Obviously you know more about available OPamps than me. Are you a part of the R&D team of ifi audio? Yes,, I order from Mouser, parts come direct from Texas. OPA627 has laser trimmed input resistors for the ultra low Ib...

    Adjusting screw tightness on Esoteric K1X helps a lot!

    Yes, you are right, an endless and super interesting field. A bit like cooking for different tastes. But we can agree that the NE5534 is best to be exchanged, and that it can be easily done. So I personally dont fear warranty problems and never had one. And you are right also with the...

    Adjusting screw tightness on Esoteric K1X helps a lot!

    Thank you! Sockets for OP amp rolling is an effective way if you want to try out and find out what matches best your favorite musical taste. And for my taste BB OPA627 fits the best. And also OPA 627BP sounds worse in a socket. (worse input guarding). And in this filter application the input...

    Adjusting screw tightness on Esoteric K1X helps a lot!

    It began last century with the Esoteric VRDS 25X and his output stage. OP amp rolling was very popular theese days in Germany. Actual pictures are from K-03XD, I changed (myself) the NE5534 to OPA627BP. An incredible huge difference to my ears. I own the N-01XD with P-02X and made the...

    Esoteric seems to sound weird after 6-8hrs of running

    yes, the Grandioso K1X is the only player with the external power supply possibility. And so it is uncompareable to all our similar gear. Do you own and use the PS1? Could you experience the same with and without the PS1? Could you find out how the switch between the internal and the external...

    Modding Esoteric Grandioso K1X

    Dear Keetakawee, all Muses Op Amps like Muses01 or Muses 02 or Muses 8820 are dual OP Amps and often used in Esoteric gear like N-05 or F-05 and the earlier XS series. And I share your opinion about the sound of these OP Amps. All these Muses OP amps are begging me to be exchanged to dual OPA627...

    Esoteric seems to sound weird after 6-8hrs of running

    I use my N-01XD without degression in sound after warm up. Maybe cleaning the interconnect contacts could help, avoid contact oil.

    Melco HA-N1Z / 2EX-H50 Digital Music Server - Owner Review (Part1)

    You can get many good tips for the Melco in www.hifistatement.net. For example you better use the Ethernet connection instead of the usb connection. And use a switch. And you can easily exchange the HDD to a SSD. My personal favorite is the Samsung 860 pro 4 Tb.
