NEWS! NEWS! NEWS! Go-Vibe V6m is here!(pre-P.S.: DexDexter, you wanted to know what Norm said, here's the following, buddy.... enjoy!)
Without Norm's endorsement, I have now coined the breed of a new amp: the Go-Vibe V6m
Ok, what might you ask is the V6m? To put it quite simply, it's just the name that I (me, myself, and I alone) have given to a version of the V6 that was the culmination of about 15 to 20 e-mails, back and forth between Norm and I, trying to get the perfect little amp built for me. Now, don't take the name V6m as official, because it's not (at least for the time being). The "m" only stands for "modified". It's just what I like to call my little wonder amp that will be arriving tomorrow*.
I like 24V. Plain and simple. Ever since I made my 18V batery back, I discovered how much better the original GV5 (with the LM series opamps) sounded with the higher voltages. And the Elpac 24V adaptor revealed an even higher range of fidelity with its greater power output and low ripple.
The V6 will not work with 24V because of the battery recharging circuit. Neither would the original 8397/825 opamps. But now with the 8620/8610 combo, they will run on 24V. And most any opamp will perform its best with its maximum allowable power provided to it.
OK, so again, what is the V6m??? The nicknamed "V6m", for the same $85, will be my own custom V6 withOUT a battery charging circuit, but that WILL run on 24V using the same Elpac 24v DC linear regulated power supply with 2.5mm DC jack (which is the same one used with the Go-Vibe V5 and V5S models; model #WM080-1950-760) and with a Blue LED light. I ordered mine with low gain, but I'm sure you can get this same configuration with high gain as well.
I don't personally care about having the rechargeability factor (especially if it comes at the expense of better quality sound), and portability isn't much of an issue anymore, since I listen to my rig at home most often... if I need to, I will use an Alkaline 9V like I always have. According to Norm, the V6 has a superior sound circuit with "superior caps" over the V5. The V6 amp is smaller than the V5, has better input/output/volume pot locations on the front than the V5 (in my opinion of course). (With the V5, the LOD cable often gets in the way of turning the volume pot).
So why didn't I just get the V5S or V5 with 8620/8610 opamps? For all the reasons mentioned above.
So before you decide to get a V5, which doesn't have a recharging circuit anyway, perhaps consider this modified model, if Norm will make one for you (a V5 with the 8620/8610 opamps will cost slightly less than the V6)... tell Norm you talked to Phil or read my comments on Head-Fi "and would like to know if you can get the same V6m (a V6 with a Blue LED, with no battery circuit that will run on a 24V Elpac with a 2.5mm DC jack input)".
I'm sure (but don't quote me on this) he would be happy to make one for you. This might work out to be a very good selling item for him. (The V5S is different and would be good for you if you plan on op-amp rolling.) He's such a great guy anyway (as I've known since my GV5 purchase experience), I have to give him so many kudos for accomodating me like this. He doesn't charge for fancy pad printed cases; just excellent sounding, elegant and simply designed, low cost headphone amps. And even better, he didn't charge me extra for this modification (perhaps because I'm costing him less money in amp parts, or perhaps it's just because he's an excellent guy that knows he has my repeat business for life).
It seems this configuration of V6 might quickly replace the V5 with 8620/8610 opamps (not the V5S).
So if you have recently placed an order, you might want to ask Norm if you can change your orders quickly.
Please don't overwhelm the guy with e-mails though. I will receive the amp tomorrow, and will answer any questions you might have based on sound quality and performance.
*Norm is aware that I am choosing to call it this, and A) he has made no official endorsement of me doing so, B) has never given me written or verbal permission to announce this custom modified amp by the name of "V6m", and C) any plans to add this particular modified V6 model to his already stellar line-up of portable amplifiers in not guaranteed to be forthcoming.
