instead of believing what I posted about Halcro’s, I suggest Amir buy a set of their amps, he will marvel at their spec’s, and he will probably enjoy their sound. Plus, he can get a very good price on them…I wonder why? LOL.
The feedforward technology in that Halcro amp (and prior, from Kenwood and others), has completely transformed the headphone amplifier market. THX reintroduced it by eliminating the inductor in the design and with it, make a giant leap in distortion and and noise. Drop.com shipped an amplifier with it in it and changed the industry forever. The amplifier was raved about by both objectivists and subjectivists.
The THX design then created an arm race among a number of companies to even better its performance. They used a composite op-amp technology (op-amp in feedback loop) which avoided THX patents while producing even lower levels of noise and distortion. Topping was the first company to do this. Check out their latest incarnation, the A70 Pro:

Check out the stunning performance as far as distortion and noise:

Distortion is at whopping -150 dB. As a way of reference, best case hearing threshold is -115 dB. We now have 35 dB of headroom!
The noise performance is better than the best DACs even though this amplifier produces more power:

At $499, this headphone amplifier costs less then the shipping cost of many high-end gear!
It is this kind of transformation which is fueling interest in what we do at ASR. The measurements have created a closed loop process with clear goals of what needs to be done to create state of the art audio products.
Same technology is now used in low to mid power power amplifiers with similar stellar results. Again here is Topping LA 90 Discrete:

It now beats Benchmark AHB2 which was also based on same feedforward technology as Halcro/THX:

Will be interesting to see if they scale it up in power some more.
Net, net, there is an incredible world of technology that you are not aware of. It is advancing in real time and provide incredible pleasure to us as true music lovers who want full transparency to the source.
"LOL" indeed but not in the way you meant it.
