There's this tendency to think cost + complexity == quality, which I think this amp shows isn't true. But also I think you have to keep in mind that a goodly number of popular DIY amps, in particular, have been designed and marketed as "second best" versions of bigger, more expensive, more complicated, and "better" amps, and still more have ostensibly been designed to be first and foremost cheap to make; as such, some
people don't see the point in putting "good" components in something that doesn't "deserve" it. (I think it was over on the other forum, but someone a long time ago made some disparaging remark about putting boutique caps on an AlienDAC, saying something to the effect of 'why put high-octane gas in a Geo Metro? it's never going to go fast
, no matter what you do to it'.)
That said, there's a big difference between boutique and, you know, gold-plated-fairy-wings-in-unicorn-blood boutique
. Sure, Obbligatos and Elnas are "boutique", but it's not like we're talking about Jupiter or Mundorf levels of "boutique", here.
|I am liking it quite a bit, it's definitely more detailed and musical than the SS and costs about the same (and is much easier to build).
I don't have a SS, but after a while listening to this amp with a decent power supply, I'm finding it more enjoyable than a SOHA Mk. I with JISBOS. Which saddens me quite a bit, because I have a lifetime supply of 12AU6-family tubes stashed away.
...and, needless to say, it's a lot easier to build than a SOHA Mk. I, as well.
Of the tubes I've tried so far - GE, Sylvania, and RCA 6AU6; JAN Philips 6922 - I'm really, really liking the Philips 6922; once it burned in a bit, it's really, really
nice. I haven't done any RMAA tests, and don't really plan to, but my impression is that it may be a bit more linear than the other tubes I've tried. To my ear - and this may just be me - none are lacking even the slightest in bass, and all reproduce highs quite well, but some - particularly the Sylvania - emphasize mids and vocals; I don't find this objectionable at all, as I rarely listen to instrumental music, and actually like
to hear what people are singing - but the Philips 6922 seems to have less emphasis here than any of the other tubes I've tried.
