I took some pics inside my Cyrus 8vs amp. I've always thought that this amp has sounded pretty good with Grado's. Very neutral! I opened up the amp and it looks like the dedicated headphone amp is a cmoy based design? or am I wrong? Funny thing is that the parts in the Cyrus headphone circuit probably costs more than the same parts in a RA-1 + I get a huge power supply, multiple inputs, selectable input sensitivity and remote control.
From what I've seen of the parts there's Elna capacitors, TPA152 op amp and a 6.3mm Neutrik jack.

Eh.. my dad has an 8vs and I never noticed a headphone out.. Are newer versions called the 8vs too?

Hello,
It's on the back of the amp.

 

[MartinB]

Doesn't seem like my images shows here. Got to get that fixed..

 

[MartinB]

Problem's solved!

Wow, I love the upside down labels - something you can actually read when leaning over from above to hook stuff up.

Anyone have an opinion?

I don't think people who know what's inside the RA1 hold it in very high regard. Kudos to Cyrus - they weren't even trying to build a headphone amp, and they've already matched it.

Of course this is just my personal opinion, RA1 fans will disagree.

Apparently something I took for granted.

I haven't had extensive experience using the headphone out of my Cyrus (if only because the headphone jack is so darned hard to reach...), but I certainly can report a pleasant experience using it with my AKGs (that includes the K340). The totally electronic control plus the remote capability is quite something too! If only headphone amps come with these as standard.

Sweet

Any idea how it fares with other cans? Now I know where the 8vs will be going when he decides to upgrade

Ay, still remember that big thread on the RA1's internals that went to hell..

The quality and cost of the capacitors, jack and op amp in the Cyrus is probably more expensive than the same parts in the RA-1. Add to that, that it has a large power supply and probably a better potentiometer too.

I have actually only listened to the amp with Grado's I'm afraid. I've owned dedicated amps in the past, including the RA-1. As I've found that the headphone output on the 8vs always sounded as good, I didn't bother with a new headphone amp. I want to say that it's not a warm amp or an amp with big bass. It's sounds strictly neutral to me. You get what's there. Sort of like my experience with the RA-1 and works very well for Grado's.
Regarding the headphone jack on the back it's not a problem if you only use one pair of headphones like I do. But I always use an extension cable so I have the jack on the front anyway

Reason I opened up the amp and had a look is because I wanted to know why I thought it sounded so good. The headphone output needs burn in and warm up though before anyone seriously judge it.

I might actually keep it or not bother to get a new amp. Hard to do any real comparison without having any amps to compare it to though.

My impressions is after long term usage, but the pics might explain why I think it sounds as good as a RA-1..

Yes, but it can't possibly sound as good because it lacks the mahogany box.
