« on: January 09, 2018, 01:00:21 PM »
Recently, my Marantz cd player keep have problem reading disc, so decide to replace with new laser len to keep it playing for a few more years. The replacing method is quite easy just need screw driver and careful when disassemble all the parts. Here it goes....

1) Removed the two solder bump from the new CD laser len (this is to prevent static when ship by vendor)





2) It should look like this after dis-solder.

HiFi Audio Equipment Discussion / Amplifier spec : THD and THD+N
« on: November 24, 2017, 03:11:38 PM »
Often audio amplifier is spec at 20Hz-20Khz, RMS 100W with THD of 0.01% as an example. The THD here in most case is actually THD +N and not the real THD spec. Note the difference in how the THD is calculated.

This weekend, we gather at Bro Marcus house to have a PK between the three power condition devices on how it improves sound on his McIntosh audio system. He is using Mclntosh pre and power driving B&W speaker, CDP is Marantz SA11S1.









Without any power condition as listen to in his original cdp setup, the high frequency details is roll off, mid range is muffler and bass control is loose. Sound stage is 1d, general feeling music is lifeless and not engaging, a lot of music detail is missing here...
So we added in the Mytek DAC into the system chain, it brings out the high frequency detail but a bit harsh and noisy, also the bass note sound truncated and do not have the well control bass drum liveliness bounce.

So next we add in CSE-RG100 power regeneration for the CDP and Mytek, power cord to cdp is using Nordost Vishnu and Mytek DAC using Cardas Neutral reference power cord, Cable to CSE-RG100 is using Nordost TY2 power cord.
Immediately we hear an improvement on mid range and high frequency detail, but bass control is still not to our taste. So we add the Nordost QX4  in the chain before CSE-RG100, we hear the QX4 roll off the high frequency details but now system become more quiet as more dark black ground, but again sound not to our taste, so we remove the QX4 from the chain as feel it does not improve the system sound.

Next we replaced the CSE-RG100 with PS audio P10 to power the CDP and Mytek DAC, regenerated voltage is set to output 240V with 0.2% distortion. Straight away we hear even better sweet high detail and mid range and better control bass note. Now the sound stage also have a more 3d effect with better placement of instrument in the sound stage.

We then power both the McIntosh pre and power from the P10, using Nordost Vishnu power cord to preamp and Hisago power cord for the power amp. Well, our jar drop, everything start fall into place, the 3d sound stage, the sweet high and mid range vocal and well control bass note. The system sound now is well balance across the freq spectrum and very musical. This is how a high end Hifi system should sound like! It is very comfortable to listen to at the same time all the high frequency detail is there and system is very quiet with dark black ground.

If anyone does not believe a few power cord change and using power regeneration condition can improve the sound should listen to bro Marcus system before and after ... the sound is 100% better... so bro Marcus kena poison decide to order a P10... a very fruitful tuning session indeed and thanks the host for the home brew coffee and hospitability. Bro Marcus and Sydney1128 and Loh, please add in your review of the sound system and which area u like the sound performance...


The final tuning setup that give best optimum sound:

wall to PS audio P10 , use Nordost TY2 power cord

P10 to marantz SA11S1 , use Nordost Vishnu power cord

P10 to Maytek DAC , use Cardas netural reference power cord

P10 to Mclntosh preamp, use Nordost Vishnu power cord

P10 to Mclntosh power amp, use Hisago power cord

HiFi Audio DIY / DIY: AMB lab sigma 22 regulated power supply
« on: July 04, 2017, 10:56:10 AM »
We spent few hours solder two set of the sigma 22 regulated power supply from AMB lab. The PCB design is quite nicely done, but supplier have send some wrong value resistor parts , so could not done the measurement till we get the right parts. The circuit is quite simple and suppose quite low noise and good for audiophile application. Originally design is use to power their own power amplifier. Stay tune for our test measurement and listening test for audio...
