Not lacking anywhere in the design. fully discrete, dual mono only 25VA (but hey that's commercial concession for ya) and transconductance topology. Now an unpopular opinion is many of these current amplifiers are actually a little strongly warm-tilted. Plenty of reviews of the 430 demonstrate such opinions and likewise the Bakoon AMP-13R has a bit of this and it's really less of a warmth issue but more of a smoothing-over characteristic. This, I'm sure is your culprit of a lack of dynamics.
Interesting observations. I haven't heard the Bakoon, but Questyle also uses current mode amplification and I don't find their stuff lacking in either dynamics or possessing a "warm" sound. Quite the contrary, in fact. FWIW, I auditioned the 430 several years ago and did indeed find it to sound "smoothed-over". Not my cup of tea in the slightest.

The CMA is another good example of current amplification.

The other day I was inadvertently playing my Final D8000 and my Sonus Faber Electa Amator 3 speakers, simultaneously, not realizing my speakers were playing music (on my Accuphase e380). I kept wondering how the D8000 was giving me the most out of the head sound stage ever! 😂

Been there! Funny what this does to our brains :D

Super interesting. Does anyone know the 430HAD’s output current ratings? The big issue I had with that and the Susvara was exactly this: a lack of dynamics.

With my 600i too low gain result in reduced dynamic. You can try to change the gain setting to max (20dB) and see if it gets a little better.

Chord Etude just arrived. Impressions soon...
You're leaving us hanging. How is it?

I get my TT2 back from repair tomorrow (after what feels like a life time of waiting). Currently I'm feeding a modest SMSL M200 DAC into it and I don't want to judge the amp on that. I will say I'm shocked at how the Susvara soaks up the power like it's nothing. Yesterday I was playing some music with a really high dynamic range and I had the DAC at full output to the Etude and into my Susvaras, nothing blew up.

I've tried this several times: there is an improvement in dynamics to a degree but it is outweighed by other decreases in sound quality which ruin the experience, so I stick to low gain. I'm thinking of buying a 600i as a speaker amp for use with actual speakers - are you saying it also lacks dynamics then, as a general rule? The 430 sounds lovely with headphones like the HD800S because it adds a smooth speaker like presentation but it falls flat for similar reasons on other headphones: perhaps I'll see the same behavior with the 600i in use with speakers?

A friend of mine regularly used his AKG K1000 with a subwoofer turned on.

As have I for an extended period of time, very solid experience :)

If you look in the thread you will find Bonesy Jonesy has the Etude with the Dave.
Not the Etude, the Mezzo 140 which was the model before the Etude. However, the underworld say the Mezzo 140 is better than the Etude !
