Although they are more temperamental and far more expensive than transistor-driven amplifiers, many audiophiles and audio professionals prefer the warmer, richer tones produced by vacuum-tube-driven amplifiers.
many audiophiles and audio professionals prefer the warmer, richer tones produced by vacuum-tube-driven amplifiers
many audiophiles and audio professionals think the warmer, richer tones produced by vacuum-tube-driven amplifiers make them preferable
warmer, richer tones are produced by vacuum-tube-driven amplifiers and they are thus preferred by many audiophiles and audio professionals
vacuum-tube-driven amplifiers are preferred because they produce warmer, richer tones by many audiophiles and audio professionals
vacuum-tube-driven amplifiers are preferred by many audiophiles and audio professionals because these amplifiers produce warmer, richer tones
although they are more expensive than amplifiers...
提示主句主语也应该是某种amplifiers，排除ABC
D，by....距离过远，会造成歧义
E correct
句意
"从句说它们(vacuum-tube-driven amplifiers)怎么怎么样，那主句的主语就应该是他们，排除ABC
D by the位置不对，有歧义。"
A项句意错了，主宾颠倒
although 让步中的they 明显指代的是 VTD amplifiers, 即--- 让步状语从句中是说： 虽然VTD amplifier要比 TD amplifer要贵更更有个性的， 所以主句的核心词必须也是amplifiers， 可以是S主语， 也可以是O宾语但就是不能是个modifier的成分。 因此
abc都是amplifier都是modifier， C 平行的逻辑有误, D 会造成歧义because后面整个是原因状语从句。
although引导让步状语从句，不要求平行
abc选项中从句中的they优先指代了audiophiles and audio professionals和warmer, richer tones，导致逻辑❌
d选项中prefer和by之间相隔太远，造成修饰不当，同时会造成歧义“produce xxx by”
although让步状语从句放在句首，不要求主句的主语一定要和从句的主语保持一致。
选项A：主句的主干是many audiophiles and audio professionals prefer the warmer, richer tones. 这样从句中they所指代的vacuum-tube-driven amplifiers变成了tones的定语。无法形成让步转折关系
选项B，C错误分析同选项A。从句描述了一个vacuum-tube-driven amplifiers不好的地方（反复无常且太贵），逻辑上转折以后需要要描述优点
选项D：preferred距离by audiophiles and professionals太远
没有仔细看E的内容就急匆匆地选了D，其实相比D来说，E更好
D中的by sb离V太远了
选项D by many audiophiles and audio professionals离preferred 太远，容易造成歧义
a选项为啥错了？？
我理解的是：前句they指代的对象应该是vacuum-tube-driven amplifiers 而不是这些发烧友和专家（audiophiles and audio professionals ）
后面有by amplifiers，所以they应该没什么问题，我感觉这个应该主要是语义上错了。
逻辑主语。只有两个amplifier才可以比较。amplifier 和 pros 不可以拿来比。

(D) preferred because they produce warmer, richer tones by结构中preferred by结构中间插入because从句,使得by引导的修饰成分离修饰对象preferred太远
