I own the WA7 2nd Gen. Is this worth upgrading to?

Is the WA7tp PSU upgrade worth the $749? I currently own the WA7 with the SS PSU, and was curious if it would be a significant upgrade. Please share your opinions.

Anyone had experience with both of these amp/dac combos? Share your opinions, please.

That's what I was thinking. I have been using my FiiO Alpen 2 at the moment with the HD 800 S and it sounds good, but I want something more high quality to pair with them. I was reading this thread: https://www.head-fi.org/threads/best-amp-dac-for-hd800-s.819287/ and one of the recommendations...

Anyone tried the FiiO Q5 with the balanced output?

I am open to all suggestions, and I will take a look at the ALO. The reason I wanted the balanced on the FiiO Q5 is because it outputs 93mW of power. That would be enough to drive the HD 800 S I am hoping.

The reason I am looking at these two is because I am familiar with FiiO products. I have owned the Alpen and Alpen 2. I recently purchased the Sennheiser HD 800 S, and have been trying to come to a conclusion on which amp/dac combo to purchase. Cavalli went out of business and Oppo has...

Anyone have experience with both of these Amp/DAC combos? What are your opinions on the sound quality of them?

Bump

So, I bought brand new tubes for the WA7 and I am still experiencing 1 occasional pop. I own a solid state amp and I have been trying to recreate the issue on it but it sounds perfect. Just having this is with the WA7, and it is plugged into its own wall outlet on a different circuit, and should...

Found some with some scratches on the plastic housing and steel mesh for $700. Cushions on headband and ears look like they are new. What do you think about that price?

Found a guy selling some HD 800 S headphones for $1,000 with minor blemishes on the exterior. The ear and headband cushions look new. Think this is a good deal?

Thank you for your reply! I will be using the HD 800 S, Denon D5000, and Fostex TH-X00. I'm trying to narrow it down to which of these Amp/DAC combos would be the best.

Looking for someone that has listened to both of these Amp\DAC combos with 300 Ohm open, or closed back headphones. I would like to know your opinions on them and if there are any significant sound differences between the two.

Okay thank you for the suggestions. I rolled the tubes again and re-seated them. The popping hasn't returned thankfully. Additionally, I have also been considering getting a new FiiO Q5 with the high power AM5 amp module for a pure solid state listening experience. Do you think this Amp/DAC is...
