That's interesting, because in my own research I found much more consistent enthusiasm for the V6 Vivid. What I recall is that people recommended the Classic if you were especially into more intimate or acoustic music, but the Vivid was generally the winner and more lively and interesting for most things. I have the Vivid and love it with the Whammy, but I'm listening with DT-880 250ohms.

But assuming those impressions of the Classic are true, I would think the Vivid would complement the HD 650's better, since Sennheisers tend toward a relaxed and smooth sound signature (that's the general wisdom, and having owned some I agree). I'd think you'd want something more lively to complement that and balance that out, rather than doubling down with the Classic, but that's just my philosophy.

Hi guys. I need some help with the wiring for the power outlet and the switch. I didn't understand the directions and I don't want to screw anything up. Could someone explain to me exactly how this is to be wired. Do I have this wired properly so far?

I forgot to mention that I also need help with the wiring to the AC and LED blue light wiring (on the switch). Once I can get this the rest of the build looks pretty straight forward. Thanks.

I am going to join in with a similar request as the previous posts.

Wiring from the main board to the IEC socket and grounding it. Some better pictures , wiring diagram, or some further explanation would be very helpful to me.

Hi, what is the output of Whammy in 8 ohms ?

Which headphones have 8 ohms impedance?

I think someone may be trying speakers....

I have/use some headphones with really low impedances (Pioneer Monitor 10, LM700, LM500, SE505 ...)

Whammy will output about a watt into speakers. It doesn’t have the heatsinking nor the transformer to do that for very long.

New Whammy in the house!

This is my first serious build and it sings!! First build was a $14 6j1 preamp meant more as a soldering practice than anything and a couple mods here and there (mostly just changing caps). So happy everything went quite well except that cutting the IEC inlet was major PITA. Took me 2 hours to drill holes on four corners and try to cut a straight line using a cheap rotary tool I got on Amazon. I'm just glad I didn't cut myself :cool: I think I need to get a work table lol I just drill and cut on the floor making a mess on the carpet!

The best part of this build is the PURPLE LED lol. It just looks so damn sexy haha. I didn't isolate the input RCA and the two 3.5mm output jacks at the back at first and it was giving me high pitch noises. So I went ahead and isolated everything at the back from the chassis and it's now noise free. Front 3.5mm jacks are input and bypass. The knob is kinda small so I'll change to a bigger one soon. Thanks everyone for sharing their builds and ideas and the newbie friendly guide and awesome design!
