周日这一玩,让BRUCE听到了DAC直入102后的力度和动态,我觉得BRUCE要摒牢不动,很难. :lol
我肯定摒不牢的. 力度为王. 是说da10吗? 可惜只有平衡输出, 不合用啊...
P8i现在只有二手 一般也就4-6k美金
另外我之前也说了 你真不如上521i的
但是P8i到底好不好你还是试一试吧 反正美国烂评如潮

当时试箱子的时候用的欧博300b单声道后级，加上他的参考级前级， 搞杰士号角王和la scala都没问题，就是搞不定heresyIII, 宽松是宽松，细腻也很细腻，但没有力度。这对喇叭脾气挺怪，对功放是又要有点功率，又要 ...
胆机不麻烦啊, 可调整的空间也很大. 不过有狗狗...
狗狗怕啥,爪子按到管子上烫一下,以后一辈子绕道走 ...

da10和dac1都是这样， dac1动态更大，这是耳机系统上感受不到的:)

wadia 521i几钱？
只怕一瘸一瘸了...
如果是高效率的号角箱(94db以上), 用300B单端胆机出来的声音那是很宽松啊, 曾在一个朋友家听过.
:P

晓得, dac1的动态就比我家的ps ultralink要大...
DAC1的动态很猛,但由于速度快,瞬态好,另外低频密度有些欠,所以给我的主观感觉是"重量感"有些不够,偏向"跳脱"而不是稳重.当然,这不算缺点,但却是它的一个重要特点.
很多老机下盘肥肥厚厚糊糊一大片就算有重量感么?
重量感应该是建立在差距和对比的基础上 同微动态的关系比较大
wadia 521好象拖拉司机有. 大概多少钱啊?
老机那种慢肥糊的低频当然不能算"重量感". 低频要有合适的重量感,与速度,密度这两个因素关系很大. 必须速度和密度配合合适. 象DAC1这样,是密度稍欠,速度偏快,听感上就不是稳重,而是跳脱的性格; 如果下盘密度大,则速度不能过慢,否则就变成滞重.
有些人会认为机器的速度越快越好,瞬态越快越好,其实也不是这样的. 速度和密度必须配合良好,方为理想.
想要微动态出色可以找找高文的MIMEISIS21解码前级2手价格应该和DAC1+CAPRI差不多,音色也好的,不过没有DCS的解码好,D家解码都带前级功能的(好象是6V,足够玩的了).
WADIA521新机远超DAC1+CAPRI的价格了,2手比较少价格同样很高的.而且关键是难觅!

Hi Rory,
simply surprised to get feedback from u guys so quick! I wl do some testing and let u know if any further assistance required.
By the way, I am in Shanghai, China. Lots of Benchmark fans here as well.

Hi Bruce,
When operating in the calibrated mode, the DAC1 is putting up to 12.26Vrms into the preamp which is undoubtedly overloading the inputs.
Either adjust the calibration pots down, using a voltmeter and test tone, or set jumpers at -10. The difference I believe you are hearing is simply a matter of volume level.
Unless you absolutely need your preamp, why not use the DAC for that and sell the preamp? You acknowledge that it sounds better this way plus you’ll put some cash in your pocket.
Call me if you like.

Subject: audible distortion at 0db jumper setting.
Importance: High
hello, I am using benchmark DAC 1 D/A converter with LHH 500R as CD transport to match with jeff rowland Capri pre-amp and m102s power amp.
Now it seems that I have some matching issue between DAC1 and Capri pre-amp.
DAC1+ pre amp + power amp combo results in less punch and dynamics as compared to DAC1 as pre in variable mode driving power amp.
Also when D/A output jumper set at 0db , there will be audible distortion on the high range which is suspected to be frequency cut-off by the pre-amp although punch and dynamics improved to a great extent.
So in a typical home audio set-up, shall I avoid using 0db setting? However as to my taste, 0db offers great dynamics and punch.
Any solution? Shall I stick to -10db setting and adjust the caliberation trimmer to increase output level?
Thanks a lot!
Best regards,
Bruce Shen
0DB时,电压输出过高使前级输入端过载:(
