Lol, just depends on design

Yeah

I should note that with the new or higher end FM gear, they have a proprietary speaker cable system called Forcelines, thereā€™s no binding posts on the amps, and their special system uses almost like huge ass banana plugs that Iā€™ve not seen elsewhere. Iā€™ve had to use a speaker tap box (simply just box with binding posts, high quality cabling and a single 3 pin for l and r, no attenuation or impedance matching stuff or resistors and whatever), since I canā€™t directly connect up to the amps

Hereā€™s a good picture of it online for reference

I wish they just had normal speaker taps on them, but Iā€™m just glad I was informed before I picked up this combo so I wasnā€™t left not being able to use them lol, but you have to use a headphone breakout box here. I ended up with forcelines 7 which better suit smaller speakers apparently

The interconnects arenā€™t proprietary, although for synergy reasons Iā€™d highly only consider their PIT cables (and the 108 mkii are only bal while the 155 is only single ended, so I needed to get some of their rca to xlr cables anyways)

This also reminds me that i need to catch up on the dac thread. 125+ messages behind.

Sorry for the lack of impressions on this stack, I just havenā€™t had the desire to listen to it after the horizon left lol. Iā€™ll move these to the main setup and put them through their places soon enough

So Iā€™ve been busy lately and havenā€™t has much time as I wanted to with this stack, but I might as well go over a few standouts (only as a combo driving headphones):

Iā€™m sorry if this all seems confused and contradictory, thatā€™s because it is, but I feel I should still at least make some sort of comment on it

Pickiness:
Why are these so picky. They can go from amazing to being so boring and unimpressive so quickly with the wrong matches, wrong music, and wrong configuration lol. Iā€™m so incredibly mixed because on some setups they are truly amazing, and others leave me feeling like I could get the same performance for more than half the cost. You can get them sounding amazing with the right combo, but others will just be entirely non worthwhile

As an example, the totaldac vs horizon on the same stack. The horizon feels so, so much more involving than the totaldac does on that setup, and I think thatā€™s really because with headphones I do prefer something a bit more exaggerated and involving than something purely honest/transparency focused. The stack is just so incredibly unhyped and even in most all aspects that while they are incredibly technical, they can come off as unengaging or not showy enough for my tastes with headphones. I also think it is limited by the headphones, to me this is really maxing out what most all these headphones can do, and thatā€™s likely another reason I prefer a dac that offers a stronger lean into /something/ rather than more dead neutral.

I just canā€™t really figure out how this stack can go from sounding almost very hifi and technical (I donā€™t want to say analytical, but almost mechanical) to incredibly organic depending on the pairing, they really adapt to whatā€™s connected to them in both source and transducer.

Even on the cables, the FMA interconnects are a must (and speaker you have no choice), other interconnects at even much higher price points just donā€™t make sense as they get beat out by the FMA ones for me from a technical and tonal perspective, they are absolutely designed to be paired together, the synergy there is critical.

I would highly hesitate to suggest these to anyone, because theyā€™re so picky with the system that you really just need to demo them somehow first (moreso than other stuff, demo everything if you can though). They have so much potential, but even the dumbest shit throws them off.

Features:
Having a mono button on a preamp is so helpful, in my case specifically for better dialing in my mysphere without having to force mono though software, pretty awesome to have. Speaking of volume, having something with one single knob and a remote is something I greatly appreciate and shouldnā€™t take for granted after the lamm lol.

High gain and gain matching:
I donā€™t really want to dick around with the gain of this system since it was already set up for ideal matching, but thatā€™s always an option that you can change on either the preamp or power which is always great to see

Trying to figure out how it sounds:

I want to call these cleaner leaning, but without the dryness or analytical sense from other cleaning leaning pairups. Itā€™s fast, very very fast, pretty instantaneous sound, transients are pretty overall awesome in both attack and decay, although I do think they are a bit faster than I think they should be in some case from a realism perspective. Itā€™s also slightly rounded slightly bloomy in a way that helps balance that out, itā€™s both super engaging and incisive. Itā€™s insanely resolving and technical with itā€™s lower level information, really impressive and while a bit more forward and presentation than Iā€™d typically prefer itā€™s so well done that I canā€™t really complain. Itā€™s just confusing since it really sounds like itā€™s taking the best from both ends of the spectrum and then forcing it in the middle without much compromise (perhaps the compromise is the pickiness lol). When it comes to dynamics unrestrained is a great word, and spatially itā€™s extremely accurate, but also can have a sense of scale and grandness that not many amp+pre combos have really been able to match.

Iā€™m sorry I donā€™t have much more to say right now, Iā€™ll get to actually describing how they sound later when I have more listening time and have a better idea of what Iā€™m hearing

But so far pretty awesome, better than any headphone amps Iā€™ve heard for the 3.2 and susvara. Will spend more time with other cans later. And try and make some more helpful pairings, comparisons, and swapping it into my main setup and seeing how it fares with things itā€™s actually made to drive instead of headphones lol

Quick note with the Susvara and this pairing, itā€™s really really really good, and likely the best example of balance in the susvara Iā€™ve heard. It does an incredible job of injecting the most energy and directness into the headphone while keeping the signature of a sweeter amp pairing, basically taking almost all the traits Iā€™ve liked about specific pairings Iā€™ve enjoyed in the past boiled down into one stack and taking it up another notch. Really great, and really addresses my main qualm with the susvara overall in comparison to other headphones.

Basically, actually making me want to use the susvara when I havenā€™t because of the mysphere for awhile now lol, back to being on more even footing (for now, until the dac comes in)

All right, the clone is in, Iā€™ll probably be able to start listening by the end of the week lol

My eyesight is a bit shit, from a distance I wouldnā€™t be able to tell it apart, but up close you can see some flaws that give it away (color seems off, some visual defects), but to someone whoā€™s never actually seen fm gear up close, they might not know. PSU is totally different, so thatā€™s another give away. Build wise itā€™s not great, switches and pot donā€™t feel good and feel cheap, chassis is somewhere similar though although not as solid feeling and not as well built.

I should note I got a fm155 mki clone, so it is a different design than my mkiir

It smells like a clone lol

Like inexpensive gear not refined cheap, or like this shit is a bit riggy cheap?

Hmmmm, nothing feels high quality to use, thereā€™s a lot of wobble, but I donā€™t think itā€™s like garbage build, itā€™s what Iā€™d consider acceptable for 200 bucks

So far, currently have it hooked up to a sacrificial headphone amp, and so far, nothing exploded, and it does have some of the classic characteristics in terms of irritations of the original design from memory. The gain is crazy high, like stupid high, but using the -20 db button takes a sound quality hit and you still need to lower things further, so been using a LPGT as the dac with reduced output low enough to not need the -20 db button and get around middle range on the clone. Once reduced to get actually good volume, itā€™s working without issue so far. But youā€™d have to do this with the original as well, so this isnā€™t a problem of the clone but of the design (corrected in mkiir from my experience)

Well. This is likely the best active pre Iā€™ve heard for 200 bucks lol. Itā€™s not really a comparison with (close enough to) the real thing so far, but for 200 bucks, man itā€™s pretty interesting lol. Most active pre at this price point are shit to where youā€™re better off passive. But like, this is really surprising for the price

New notes, there is a bit of noise floor, and honestly I do detect some burn in as it sounds better today than yesterday.

Itā€™s really hard to compare differences because itā€™s not even close to the real thing, but Iā€™d say itā€™s a clean and forward sound with more of a lean toward that cleanliness than the real thing tonality wise, and much less refined. Really hard to compare anything else because the real thing blows it out of the water otherwise, but I guess it does sound somewhat like an FM to some extent. I would just personally say that so far real FM gear is more characterized by itā€™s incredible technical performance, which this doesnā€™t really have and almost lack of clear signature, and imo this isnā€™t really that. But it doesnā€™t have to sound exactly like a FM to sound good, and this does sound quite good regardless.

I canā€™t really complain for 200-300 bucks, I really hate to say it but it does have pretty awesome price to performance. Then again, thatā€™s achievable when you steal a phenomenal design I guess, even if you cheap it out and implement it lacklusterly, itā€™s still going to be better than most anything else you get at the price point.

I really would want to suggest this to anyone looking for a cheap preamp, but honestly, I donā€™t know if I could considering this is basically just blatant theft of a design lol. But I guess if you donā€™t care about that, then this is super impressive for the price, really want to try a matching clone power amp, or a higher tier clone preamp lol. I also hear the clone Darts are pretty solid as well. Perhaps pick up a nice used legit preamp instead at the price point, but I guess if you donā€™t have morals the clone is nice lol

What a great journey! Thanks for buying the clone since I never would have. Itā€™s an interesting thing to analyze and I always enjoy reading your impressions.

And Iā€™m glad youā€™re always here to ask the important questions no one else dares to.
