WOO-HOOOO... WA7 "fireflies"!!! - Page 43

post #631 of 1404
Use high impedance with HD650. Also in order for WASP I event to work go to School website and download their driver instead. During installation you will need to remove old driver first than install the new one

Thanks Olegausany for the input.  For the website, did u mean to write the "Schiit" website and use the Schiit Unified USB drivers?  If so, I guess I can remove the Woo Audio-provided driver and install the Schiit USB 2.0 driver, but the WA7 uses the C-Media 6631 USB chip and I'm not sure which USB chip the Schiit line uses.

 

Has anyone else had luck with this setup?

I'm also using the Schiit driver and got no problems with WASAPI Event mode. They use the same USB controller.

Thanks for the confirmation PleasantSounds.  I will change the driver, see if it works for me and see if I hear any change.

Oh man. My fireflies arrived on tuesday, it's the best amp i've ever had. I have a Swans M50W connected via RCA. I just flip a switch in the back and switch from speakers to headphone. also, having 0 noise at almost all volumes on the headphones is massive. My last two amp setups(schiit Lyr + Bifrost, hifiman he5) had alot of noise. Listened with Shure SE535-CL and LCD-2's so far and it drives both nicely.

Congrats. Mine is very quiet too.

 

How would you compare WA7 to Lyr+Bifrost combo?

The only noticeable difference from a memory standpoint is sometimes the Lyr made my LCD-2s trebles sound harsher than it does with the WA7 and comparable volumes. I honestly can't tell the difference in the sound quality(besides how quiet it is) because I sold the Lyr +Bifrost before the WA7 came in. So no side by side comparison for me. I switched because besides my LCD-2s I'm becoming more of an IEM guy and you couldn't listen to IEMs with the Lyr at all, even turned all the way down.

Without other information, I'd say you have one tube that probably had a manufacturing defect. Welcome to the wonderful world of tubes. I bought 4 NOS Chatham 2399 tubes for my WA3. Two sounded pretty good, with a little residual noise, one sounded very good, and one had a manufacturing defect that caused it to arc over, causing the connected headphones to make a VERY LOUD POP as if someone had fired a .22 caliber revolver. My rule is to test unknown tubes with an inexpensive and disposable headphone before connecting the really good ones. All had tested good by the seller.

The quieter tube was darker when off inside, a darker color not as shiney the metal plates etc.  When turned on the darker tube actually is brighter glowing with about twice the glow of the other.  It has always had more glow.

If you switch the tubes between channels, does the one with more glow stay with the tube or the channel? If the darkened glass tube has more glow in the other channel, then I think you have a tube that will fail prematurely. It happens. If the other tube (normal looking glass, not darkened) becomes brighter when the switched between channels, then that channel may be putting out a high filament voltage.

good idea!  will check tomorrow and then assuming it is just the tube swap out with a new set i had bought for emergencies (is making me feel clever now) otherwise I should talk to Woo first so I don't damage another set.  I should assume if the amp is putting a high voltage to the tube that would cause this premature death he would cover fixing that and replacing the tubes seems reasonable?

My WA7 is being delivered on Monday. Can't wait! :basshead:

post #642 of 1404

Checked and it is the tube which is brighter, not the socket causing the tube to be brighter.  Swapped in the spare set of Cryoset tubes I bought and it is back to sounding great again... even better then the original EH tubes Woo sent me.  Could be my reaction to slowly losing quality on those tubes or perhaps the Cryoset really do just sound better. So I guess the question becomes are the original EH tubes purchased through Woo warranteed at all? They expired unusually fast and were pretty costly so I am hoping there is something to be recovered here. They were clearly defective as these sound much better then those ever did.

WA7 came in today. Man this thing is built like a tank lol, didn't expect it to be as heavy as it is. Set up went fairly smoothly... the tubes were a bit a pain to get in (I was afraid I would break them if I applied too much force). The DAC portion didn't show up initially but the user manual pointed me to the USB drivers on the Woo website. Installed that and all is well :D

 

Starting to listen now :gs1000smile:

The good news is nothing wrong with the WA7. Tubes are not very far removed from incandescent light bulbs. Happy listening!
