Suburb or Town: Adelaide Hills State: South Australia Payment Method: PayPal, EFT, Cash Reason for selling: NLR Further information: Bought off another member in October 2020 and have since modded it with Copper around both Power Supplies and twisting the cables. Will throw in a pair of 80cm Swamp balanced XLR cables Below is copy and paste from the original post. Purchased from ShenzhenAudio in July 2020 - Current price for the upgraded usb model is $2200 I believe. Free shipping included but buyer pays insurance if wanted. Not particularly well known in Oz I don't think but absolutely packed with features - a full dual mono design with dual ES9038pro chips. This version features the optional upgraded USB interface which includes an upgraded power supply and 2 x Crystek CCHD-957 active clock and supports DSD up to 512k. Comes in original box, has remote and will throw in a free unopened Supra 2m USB cable so the new owner can enjoy the amazing sound. Two-chip ES9038pro decoding method. Two high-quality toroidal transformers, a total of 13 groups of linear power supply. Built-in specially designed Italian Amanero USB module, original license license. USB module added to isolate the chip, you can isolate the computer to the audio system interference signal. Supports USB, I2S / DSD single-ended signal (RJ45), I2S / DSD balanced signal (HDMI), oaxial, BNC, AES / EBU balance, Optical total seven-way source input, all ports support DSD input. Analog audio output port includes standard RCA single-ended output and XLR balanced output pair. Display with VFD display, the display exceptionally outstanding. Use physical key operation. Support 0dB ~ -127dB digital volume adjustment, 0.5dB level. But also has a remote key to skip the volume adjustment function. Support a variety of digital filter mode settings (see user manual). Can be arbitrarily selected, different filter mode, the digital filter attenuation characteristics are different. Supports decoding of internal digital phase-locked loop bandwidth settings (see user's manual for details). Support Deemphasis to increase or turn off. The display has 4 levels of brightness adjustable. Adjusted by remote control. Remote start, standby function. Most of the settings with memory function, turn off the opportunity to automatically save the settings, restart the settings. Dynamic range> 135dB Distortion <0.0002% Stereo resolution> 120dB RCA unbalanced port output amplitude 2Vrms, XLR balanced port output amplitude 5Vrms. Machine size 430 * 320 * 90mm Machine weight 7.0kg You can read the full specs here https://shenzhenaudio.com/products/l-k-s-audio-lks-mh-da004-dual-es9038pro-flagship-dac-dsd-input-i2s-coaxial-bnc-aes-ebu-for-dop-usb-i2s-optical-audio-decoder?variant=29703030833212 Lots of reviews on various forums such as https://www.head-fi.org/threads/l-k-s-audio-mh-da004-dual-es9038pro-dac-van-dammes-double-impact.840938/ https://theaudiostandard.net/thread/4743/lks-mh-da004-dac https://audiophilestyle.com/forums/topic/31270-lks-audio-mh-da004/ A quote from one user review "OK, so the nitty gritty. I have TWO of them in two systems and could not be happier. I had foolishly jumped in and paid even more for a Schiit YGGDRASIL until I received an LKS MH-DA004 and the difference in audio quality was obvious. So I sold the YGGDRASIL and purchased a second LKS. Note, the YGGDRASIL DAC is a fine unit, but the LKS is better. Cleaner reproduction generally on classical music, particularly with larger ensembles where the LKS reveals more detail of the individual instruments playing, has more air and delicacy and eliminates traces of digital harshness" Link to comment Share on other sites More sharing options...

Atmaj Posted March 9, 2021 Share Posted March 9, 2021 May I know why would someone put copper plate around the transformer? Link to comment Share on other sites More sharing options...
Gbickle Posted March 9, 2021 Author Share Posted March 9, 2021 (edited) Shields the EM and EF sensitive electronics from the Transformers. Edited March 9, 2021 by Gbickle Link to comment Share on other sites More sharing options...
Atmaj Posted March 9, 2021 Share Posted March 9, 2021 Hmm..... copper is a non-magnetic material and it won't shield any electromagnetic induction, you need a ferrous metal for that like iron sheet. Link to comment Share on other sites More sharing options...
Gbickle Posted March 9, 2021 Author Share Posted March 9, 2021 (edited) Copper is the most reliable material of choice when shielding from radio frequencies because of its ability to absorb both magnetic and radio waves. It is also highly effective in attenuating magnetic and electrical waves. Of all the metals in EMI shielding, copper is the most reliable because it works best at reducing both magnetic and electrical waves. You can find copper in just about any place needing EMI shielding from hospital equipment to basic home computers. Copper costs more than other alloys or pre-tin plated steel. It does, however, have a higher rate of conductivity, which makes it so effective as an EMI shield Edited March 9, 2021 by Gbickle Link to comment Share on other sites More sharing options...

Copper is completely diamagnetic, a static magnetic field will go through it like through air. However, it is a very good conductor, and a changing magnetic field (like from an AC transformer) will cause eddy currents in the copper and won’t be able to pass without substantial loss of energy. 2 Link to comment Share on other sites More sharing options...
