Icenine2 rightly ask at the Cavalli Liquid Lightning thread : what is the subjective influence of the visual aspect of the amplifier on the objective results that can be achieved with a blind test freeing the visual aspect of the amplifier ?
Yes. How it "looks" is the benchmark. I would love if one of the headphone gatherings had a blind test between different amps of every ilk. Its not like speaker rigs. All you'd have to do is have the phone cable switched to different amps behind a blind.
We have carried out such a single-blind test on 8 September 2013 with four amplifier with headphones Stax SR 009 (see link):http://www.head-fi.org/t/681814/amplifiers-shootout-for-stax-009-eddie-current-electra-audiovalve-rkv-wooaudio-wee-stax-srm727-srm007t2
The most expensive amplifier and the best (and the most beautiful) on the paper of the lot (Eddie current Electra) was indistinguishable from two of the other three amplifiers (less expensive and less rewarding aesthetically) : The Stax SRM 727 and the combo RKV + Energizer Wee.
The right question was to know what would have been the classification of beautiful amp (BHSE) or less beautiful amp like LL in such a blind test, in comparison to these other amps?
We will probably never know the answer, but my intuition tells me that we would have probably had some surprises, such as those obtained with our blind test of our 4 amps of 8 September (for the record, the results of our blind test of 8 September did not show significant differences between the Electra, the combo RKV-Wee and SRM 727, unlike the SRM 007t2 who got a very bad score (significant difference)
