    Four years after the L.K.S DA004: the Musetec DA005 DAC

    全新設計的電源系統 音響系統裡的電源,極其重要。我們為DA005設計了高級電源再生系統,猶如兩個蓄水塘,一組放水的時候另一組蓄水,循環交替。在精心設計的控制邏輯下,蓄、放是完全隔絕的,互不影響,從而可以在很大程度上避免市電雜訊對DAC主電路的影響。而另一方面,由於使用傳統的鐵芯電源變壓器供電的電路都存在負載調整率差的問題,進而導致聲音動態被壓縮,密度不足,新的電源系統則不存在這種問題,安靜、充沛、高素質的能源供給DAC電路,可以重播出最為真實的聲音。 DAC供電電路中,我們大量使用了凌特...

    L.K.S. Audio MH-DA004 Dual ES9038PRO DAC - Van Damme's double impact?

    Dear abrahavt, have you tried LKS MD-003 mk2? I guess you are saying about the 004, since a FAN IS USED. I HAVE COPE DOWN A SHORT PIECE from HONG KONG forum, users complain about the heat, it cause unlock besides reducing SQ. "但更明確的一點是個人聽感~~9038的溫度高到大約46度以上的話音質真的要折損不少,相對之下40度的表現是全面勝出毋容置疑," My...

    Gustard X20pro DAC (ES9028Pro)

    Hi guys, may I ask a question? To avoid the pitful USB XMOS U8 input and cost a lot to build a better USB DDC with clean power, how can I use coax, RCA, or HDMi from my portable PC (widow 10) to the Gustard X20 pro (no U)? Can you disclose the sequence/ steps here if it is possible, thanks.

    Oppo Sonica DAC (an affordable ES9038PRO Sabre DAC)

    Have anyone compare to or own a LKS MH-004 DAC? It costs lot more. 004 use twin ESS 9038pro for stereo and run at higher current (much warmer in temperature). I was seriously consider to buy the MH-004 till SONIC DAC comes out.

    Dear Englishman,   I am interesting to witness the jansen capacitor that replace the X capacitor (YKWIM).  By the way, no offense for the title, I went to Sheffield to gain a PHD deg. from the Engineering Materials dept. (actually metallurgy dept. long ago). The master degs were obtained in...

    LKS Audio MH-DA003

    Dear 0b00, Thanks for the reply. LKS shows the new model of new DAC; 9038pro dual on the Tao Po net, so, it should be official. Your interpretation is correct. They do mention few points like upgrade the USB board than the original Amanero, that  add up the cost of RMB 600, 9400 to 9900.  They...

    LKS Audio MH-DA003

    Dear b0bb,   LKS already announced in recent days of a debut MH-DA004, the 9038pro dual model, the price goes up to 9800 RMB. I wonder what the DIY enhancement works or not for not harsh sound. Specially major issue is on the XO model, 570 or 950? May be I should ask for a socket to ease the...

    LKS Audio MH-DA003

    There is one Canada exasound  ES9028pro  USB DAC on the market, cost around US$ 2500-3000., more expansive than the $1300 on LKS MH-DA003 I think. Sound quality? see   http://www.exasound.com/StartHere/exaSoundDACs-Features.aspx It has no internal power section, something good or inconvenient?

    LKS Audio MH-DA003

    Dear Bobb,   It is not fair, but I still like to ask a stupid question. It seems to me, LKS release the next version of MH-DA003, the MKII, preserve main XO, the I/ V OP, diodes, and many other items. They or their R & D engineers must read this forum and made some test. What would you think...

    LKS Audio MH-DA003

    Sorry, I have not hear one, but limited information to read the page on the Tao Bao network China , its on the recent sales list with 82fs clock (no change on the main OSC?),  it seems there is no face lift for the model MK II. Perhaps a re-design of the main board. I am very curious about it...

    LKS Audio MH-DA003

    Sorry, corrections, it is ES 9028pro and 9038pro, not any 2028 or 3038. May be same block diagram and function do not represent exact layout.  Interesting. Some one saying that, 9028pro good at two-channel , and 9038pro good at multi-channel, really?

    LKS Audio MH-DA003

    Just read about the new generation ESS 3038 pro, and the obslete of 3018. Curous about its development on the market. Just before I like to step in the cleared water, it is getting muddy. May someone try distinguish the difference btw 9018 and 9028, since it seems interchangeable, an upgrade?
