The PA2V2 Appreciation Thread - Page 38

post #556 of 694

My Pav2v Drive my Dt990 250 effortlessly even with the gains at low level,let`s say,about 12 o `clock.

 

By the way i was having some sound issue with the sound coming out from the Pav2v.So i contacted Gary and he without a blink of an eye send me a replacement unit while i was sending to him my my first one.

Than the shame i felt when i realized that the sound issue was from the interconnect cable Clip zip->Pav2v.....so i told honestly it was my mistake and he did not worried about it.Rare agreeable person ,considering is a running business one.

 

Ps:the strange is that i were using as well other interconnects whit my first amp and it seemed the was the amp indeed.

This guy claims to be selling an improved version of the PA2V2 with more powerful batteries, has anyone tried it?

He's selling an "improved PA2V2" for less than what Gary sells it? That alone should be suspicious.

The problem with this eBay ads, is that there are a lot of error in the description that makes me wonder if the seller even know what he/she is selling or not. First of, PA2V2 runs on 2.4V (two 1.2V rechargeable NiMH) instead of the 4.5V he is talking about (or 9V that he is using). Second, the amplifier chip inside PA2V2 has a max supply voltage limit of 5.5V. Give it 9V and you will actually fry it. Third. the seller refers to the amp as PA2V2 at first, then call it a Cmoy at the end. Well, those are two totally different design, so which is which? Last, 'impedance matching headphone'? Seriously?

Actually, selling PA2V2 for less than what Gary is asking for is entirely possible, consider better built amps have been sold for less. Just saying...

^ Fair point, but as you pointed out, it may not be a PA2V2 at all.

I asked Gary about it before I bought my PA2V2 and he said this amp has nothing to do with him and is most likely just a cMoy or other generic amp.

I just got mine. It works, I guess. I'll have to listen to it for a while longer before I can make it out but so far, I did notice a very prominent EMI from my Android.

post #563 of 694

Have had my PA2V2 for over a year now, it's wonderful to have on the go. Haven't had a single problem with it yet.

 

Also, Gary's product service is just amazing. Recently moved to Fort Worth and lost the AC charger, was manually taking the batteries out and recharging them. Asked Gary if I knew a place where I could buy a replacement, and he is sending a USB charger replacement free of charge. Just an incredible guy.

 

If he ever ends up making another amp suited for home use, I'd be a customer in a heartbeat.

I mailed him about the EMI and he said that it often happens to new amps because they battery gets knocked out of it's housing during shipment.

 

I opened it up, re-seated the batteries and all of the EMI was gone in a heartbeat. :)

Just emailed him about ordering a pair. I'm excited for this amp and can't wait to break them in.

post #566 of 694

This amp does not need breaking in, it doesn't have any moving parts or tubes, just a couple of chips...

Yes, I meant more along the lines of personal acclimation and gain tweaking. Pardon my lack of specificity.
post #568 of 694

The fact he has to mention the PA2V2 instead of his product standing on it's own, is further credit to Gary.

This is my first headphone amp. It pushes my headphones that bit further. I don't think I'll be replacing it any time soon

post #570 of 694

I'm using this amp with my HD650s right now, but, when I ordered it from Gary, he set the gain/etc to be ideal for my HD 518s  (which are 50impedance I think).   So,

I think I have to go into the amp and adjust the gain or something, to match better with 300imp,  I think from reading in here, that I just open it up, and turn the 2 blue screws clockwise a little bit.  If anyone has set this up for an HD650, that would be interesting to know.  I did email Gary about it yesterday, and I figure I'll eventually hear back from him.  But, I thought I'd post here also.   So far, I really like the amp, because I don't have a very big budget.

 

I don't have a DAC yet.
