Quote: Originally Posted by vo328 I wonder how same/different the GV3 & GV5 sound if both have the AD8620 in them. Quite different actually. Go-Vibe V1 - V4 essentially sound very similar, given that the same op-amps are used, and all are powered by a single 9v battery. The V4...

Quote: Originally Posted by jamato8 I don't know the topology of your amp. Can it use both single and dual opamps? Both versions of the Go-Vibe V5 use a dual op-amp for output L&R and a single op-amp for output ground. The virtual ground, which is now free of the heavier loads...

I would like to make it clear, that the whole point of the Go-Vibe V5S is to allow easy op-amp rolling for those so inclined. The op-amps supplied with the amp are mearly a place to begin, not neccessarily intended to be the ultimate choice. As I already posted in another thread, there will...

Quote: Originally Posted by Aflac I'm pretty sure it's not possible make any conclusions until the units are out and heard by lots of people. By the way, Norm is including the OPA2277, and not the OPA2227 - apparently, these are two different op-amps, and Tangent doesn't have info on...

Quote: So, Andrea, will you be ordering a Go-Vibe V5S from Norm, or do you intend to keep on posting here about it based solely on theory and extrapolation of op-amp impressions from other amplifiers? Fair question And the answer: Quote: Originally Posted by Andrea...

Quote: Originally Posted by M3NTAL I wonder if current GV5 users can upgrade at a small fee. First of all, let me make it clear that the Go-Vibe V5 continues as before with the surface mount LM6171/2 op-amps. The V5S is a suplimentary model, using a different PCB which was...

Quote: Originally Posted by Andrea IMHO no, the Go-Vibe v5 doesn't compete. You gotta hope the M3 is better sounding -- or I would stop looking at headphone amps right now, and just stick with the (not half bad, really...) headphone out of my Pioneer A-209R or something. My customised...

Quote: Originally Posted by Spyro Why do amps seem so ridiculously expensive relative to complete systems? I assume because production volume is so low and that they are all hand (custom) made? Well. I don't have the time, as I'm sure most of you don't, to read all the...

Quote: Originally Posted by Andrea IMO the chips are what creates the basic sound signature (which the 3 channels help worsen, especially for the LM6171/2). Funnily, the only instance I remember where I liked the LM6172 was when I put it in a Practical Devices XM3 (2 channels with...
