DIY前级

[hugoo]

不是严格意义上的DIY，还没那本事，就是买套kit回来自己装那种，目标是个前级，要求是
1. 有胆
2. 有平衡输出
3. active (not passive|) preamp.

目前看上的candidate有两个：

1. Audionote L3 Pre-Amplifier with Transformer-Coupled Output - Balanced or Single-Ended Output
http://www.audionotekits.com/l3linemk2.html



2. K&K Raleigh Audio Extreme Line Stage Kit
http://www.kandkaudio.com/linestage.html


设计上看，K&K是balanced design from input to output with differential class-A triode parafeed output stage, audionote是single ended design,但也可以有xlr output.

问题在于没法试听，光看电路设计的话，有没高手能说说大概的风格取向？

除了这两种，还有啥别的选择？
