You aint see nothing yet, here in HK, the one in my home is too ultra heavily modified to the point that those 'LITE' or alike from Big6 can really rest their place at the reclamation site...
This DAc can be good or even great but must after a heavy modification.

改到咁肉酸....見到都冇胃口.

搞咁多野不如買kit diy.

改到七彩, but 太着蹟啦!!
N年前, 摩到七彩, 我諗連 Mr. Pun, the designer, owner of Monarchy Audio 也認不出來, 所有電容, 穩壓 RC1515 改做 LT317 and LT337, 改完了無痕蹟, 識的就知行事不易, crystal 改 self-regulated buffered TCXO, 原位垂直裝, 免飛線檢拾雜訊, Op-amp IC 改哂唔在講, OP627BP and AD797AQ, 電容好多年前已選用 digital 特別好的 Sanyo OS-con, Rubycon ZA, Panasonic FC and HFZ, 原廠D 台灣雜牌電容爭天共地, 大改之後, 外觀冇變, 我改機要求如此, 儘量唔飛線, 但聲厚實, 清甜多了。
Just for sharing!

The digital receiver 75175 耐不久會神, 所以廠原已用了 IC 座, 真好彩, 買到軍用 Ceramic 75175, 如買到 54175, 又會再試, 改用之後, 未燒過, 又加了 digital signal lock 燈, 成架醒神哂

那時份工好緊張,忙不透氣, 改機用來減壓, 把工作上的煩惱一一忘記, 一樂也, 現在反為沒那好心機啦。我亦發表過將 Lite DAC-AH 改正為負相 Buffer 輸出,負負得正, 亦好多同好照跟。同樣地, 改完之後和原本的外觀沒甚分別, 只是那八粒熱得發燙的 TDA1543 各自痴上散熱器, 望落去仲壯觀左!!

改機亦要因架機特性黎改, 呢架 DAC-AH, 聽老琴真有獨特韻味, 聽完唔想聽其它機, 其弱點, 高音濛D, 粒 buffer IC 用 OPA134 相輔, 亦恰到好處。

呢d咪麼機喇，要靚，大把靚樣hifi la!

個網條鬼講連Audio Note 4 都唔夠拒好聲!

"""The modded behringer was put to test with the Audionote champs: DAC4 ad DAC2. Both have huge investments in blackgates inside, better tubes, PIO caps etc.
DAC2 has the good old BB PCM63 and DAC4 has AD1865.

Behringer was for the first time an equal fighter. Even with the 17 000 Euro for DAC4 (plus 1000 Eu for blackgates and upgrades of the A-Note) the Behringer sound was in my opinion more interesting, with wealth of details presented in a very natural fashion. Behringer was drawing me into the music. Audionote DAC4 had to fight very hard to match that.
After 2 hours - the scale started tipping on the Audio-Note side because of long warm-up of Blackgates. But the fact that such battle was almost equal - is phenomenal success. Behringer is a real mature champion. In my case - the cost did not exceed 200 Euro. Even without my cheap buying price and with somewhat more realistic lampization price - the total cost should not exceed 800 Eu. Wow ! """""

ONE YEAR LATER

I have an audiophile friend who borrowed my Behringer and he was blown away and he sasid it is the best CD sound he ever heard and he heard a lot.
So thats how an idea of a commercial production at Service was born.
I designed the new Behringer machine and Waldemar built his first DAC from sctratch (what a rhyme !)
My design was to make use of the Ultramatch with the best of everything we can come up with.

Tadadada drums rolling - here comes the world first Lampized Boxed Ultramatch on Steroids. A monster of DACS.

Without a need to skip to the verdict here it is: the sound of this monster is the best I ever heard from CD period. It beats the Audionote 4 and the Buffalo and the Wolfsons and the Satch - it beats them all. Such ENORMOUS power, slamm, resolution, not even the electron microscope but a whole goddamn HUBBLE telescope into the musical event. This experiments almost redefines my whole thinking about whats possible with digital.

I drove it by my squeezebox (untouched virgin one) and the result floored me.
Enough bullshit - here is what I did (by the good hands of Valdemar)

I used a large box because there is NEVER enough space.
I cut away the empty parts of the Behringer's front panel (I mean the alu profile) so the shorter "version" fits inside
I upgraded all 5V carrying caps on the main PCB with Oscons (mandatory).
I bypassed all circuitry of the digital input, transformer and selector MUX and I wired digital in - straight to the chip input leg via just one series cap 10 nF - as described above.
I connected the AK4393 chip outputs to the tube grids via small 10 uF/ 6V oscons in series.
Opposite phase of DAC output is left unused.
I designed a VERY oversized and overspecified power supply for the anodes: with 50 VA core, CLCLC filter, two 40H chokes, one (first) pio cap 1 uF / 600 V followed by a 470 uF rubycon and then the GIGANTIC vintage siemens 1500 uF / 385 V .
The tubes are e88cc philips goldpin SQ series in SRPP config and 300 Ohm cathodes.
The lower cathode resistor is bypassed with an oscon 470 / 16.
Ua = 220 V
The rectification is provided by a symmetrically driven dual diode tube 5u4C
The total stored energy is BIGGER than in most amplifiers.
The heaters are DC and regulated. We overheat the tubes by just 1 % where they sound more open. We used a 4004 diode from center leg of a 12 VDC regulator to the ground, making it a 12,7 VDC regulator - just for the tubes in series heater arrangement)
