Is it possible some comparison with bass of Penon Serial or of Dunu Vulkan ?
Thanks.

Serial offers way more neutrality, not as bass laden, bigger soundstage yet still slightly warm, cleaner pace.Vulcan more disjointed and not as congealed as Legato, plus has treble top-end added, also cleaner pace and while noticeably nice low-end, not as much bass as Legato.

As far a bass specifically, the twin DDs of Vulkan have more texture and still are missing a slight texture, as that is their personality. But bass tones remain placed into a zone and more controlled. The Serial bass is the most neutral and natural of the bunch being also the most real and correct. Where really I rate them most bass Legato plus the Legato bass is less defined. Vulkan is second and the Serial third, where the Serial is probably the most well rounded too?

Nice review Timmy, somehow doesnt feel as harsh in writing as on your channel!
