@marekm What do You want to know? From my perspective all I can say that FT5 simply outperforms Sundara which I also have in my possession but we must take into consideration that these two represent different sound providing approach. While Sundara is bright and by that more resolving, it tends to painfully sparkle in upper regions with accompany of sibilants and harshness when plugged into wrong gear - in my case it’s Fiio K7 because this type of planars are not comfortable with THX AAA DAC/AMPs. This places Sundara in the lore of headphones which are good in only specific genres and with specific devices. Which obviously is not so good thing.
FT5 on the other hand are more versatile thanks to their „relaxed” but still technical performance which can inform You by their timbre if they are compatible with the source (which in most cases IS compatible). This happened to me when I plugged them into Fiio K9 - sure, they became massive and bloody great than on K7 in terms of sound but still I was able to hear this clinical aerated hiss which is characteristic for Sabre DACs. This kind of tuning tells a lot about these headphones performance which makes them even more special.
My initial impressions were very surprising - even for myself because right after putting them on and started playing music I just… went with their flow. They didn’t wanted to serve another show-off type of sound with peaks and dips here and there. Instead they welcomed me with slightly dark but warm timbre which was completed with organic highs and natural presentation. That overall literally hugged me and made me experience my music library in this comfortable type of way. I must say that I was straight prepared for critical listening but ended up with simply enjoying what I hear.
And this also made me thinking… that I have already had VERY similar headphones for testing. Sure, they were not exactly FT5 but if I could just do a little play with the EQ… And this thought became even stronger and more clear when I switched velour pads to pleather ones - when the soundstage became brighter and richer in details.
A little more rounded bass with a pinch of a sub punch… a little more pushed forward midrange… and a little more air and definition in the upper region… and we have improved and organic Meze Lyric. Go on, You can crucify me - hell, I’m also not completely sure and I can’t wait to make this one-to-one comparison when Lyrics will be available again in my friend’s shop. But I’m in pure awe what Fiio managed to serve us for a fraction of costs which are usually spended for headphones reserved for those with more roomy wallets.
And when the revelation time passed I started to experiment… K9 as You have read above gave me massive and very impressive soundstage with great definition, K7 a little less but still enjoyable presentation… HipDac 2 on the other hand made them more energetic due to pushing the midrange forward but by the cost of slightly boosted soprano region which was immediately noticed by my ears and determined me in limiting listening to more „busy” songs. Fiio KA13 is waiting for it’s turn but I have a strange feeling that these will like each other due to this dongle’s neutral behavior.
… with all of mentioned above FT5 presented different face but in none of these specific situations I was in totally no-no state about what I hear. They are very forgiving and constant in terms of chosen source but depending from Your taste You will immediately notice if the sound is right for You - after all You can still finally tweak it by pad change in the end. For me AKM is the way - for relaxed, natural presentation and dynamics when You decide to listen to more fun songs. Burr-Brown could also do wonders but I think it will be possible with more advanced models.
I don’t know if my jibber-jabber was helpful or did I just added more coal to the hype train but… I’m totally sold by them. They just showed me that I don’t need always to have everything-in-my-face. Instead I received enjoyment from simple yet satisfactory rich and detailed sound. And I’m still experiencing it while discovering my favorite tracks once more.
