Of course there is always some loss of transparency that cannot be avoided but it is minimal and the improvements more than make up for it

The Broadway upon initial listening is impressive: line-out from my SP1000 to my i4s. Sound is full bodied. Want to compare it to my V281 next using my Abyss headphones. So far, this amp is a definite 'go.' Maybe it will replace my V281s...

Not sure if I like the 11:00 volume starting placement though.
How was background noise with the i4s? I have the i3s and would be interested to evaluate how the Broadway would work with IEMs.

I didn't notice any background noise with the i4s and this was with both low and high gain.

I tried 64 Audio U12T with my Formula S Powerman. Sounds great but there is some hiss, which is covered up when volume is turned up to normal listening level.

LOL...I never tried an IEM when I had the Formula S/Powerman. Did you set it at Low Gain? I don't think the Formula S was designed for IEMs. Definitely for the i4s though as I don't consider them to be an IEM and they sound like over the ears anyway.

@cj3209, how does the WA11 compare against the Broadway? I noticed that you have both amps in your signature? I just picked up a WA11 and was curious.
I've never really directly compared them as they have different purposes for me: portable vs. desktop/trans portable. The only thing I can say from memory is that the Broadway has a blacker background and seems to power the Diana PHI better than the WA11.

Well, I thought the Broadway was good, the Formula S w/Powerman is insane; took it to another level.

After a brief comparison with Broadway and Formula S using both i4 and 1266 phi cc, the Formula S sounds like a live concert; vocals are full-bodied, fleshy, and palpable. I'm using hi-gain.

I think it would cost a lot more money to improve. I stayed up last night till late listening to roon via hi-res files...wow.
does the gsx mini enough juice to drive ab1266? i attemp to get one too
