I love my EVO 300 integrated paired with Beyerdynamic DT 1990 headphones!

I've had a DV 336se for a few years for an office system. I think the amp is really good - for the money it is amazing. I use this amp with 250 ohm Beyerdynamic 770 headphones - I think it is a really good pairing.

A couple of weeks ago I made my decision and today I picked up my EVO 300. My initial impression is very positive!

I found the DT 1990s and the Woo WA 2 to be made for each other.

Now that you have spent some time listening with your Evo 300 I would love to hear your impressions.

I am curious as to why your numbers are so much different than the ones that I listed.

I ask this question because I exchanged a few messages with a rep at Upscale regarding the output of the EVO 100. I first asked about the output at 250 ohms due to the fact that I'm currently using DT1990s - the response was that the output would be "about 1 watt". As a follow up I asked about...

What question is the "service department" responding to?

I hope this question is appropriate in this forum. When selling an amplifier is it best to list as a package including multiple sets of NOS tubes or to sell items separately? What do you think? Thanks

Thanks for the reply. My upcoming move and retirement will necessitate a change from having separate speaker and headphone systems to an all in one. One consideration is the EVO, probably just the 100. Since I posted this thread, I had a chance to spend an hour or so with a EVO 200 at a nearby...

Have you sent an email to Woo? In my experience they are responsive and helpful.

Anyone have any experience with this integrated as a headphone amp? What, if any, dedicated headphone amps have you compared this amps headphone section with? Thanks for any input.

Anyone know the going rate for NOS Chatham 6as7g and Tung Sol 7236 tubes? I bought some several years ago, I have been looking around but I'm not seeing any on the market at this time.

I have been using my 1990s with my Woo WA2 for some time now and continue to be thrilled. I also favor the analytical pads. Of course my tube preferences will be of no use to you. I previously owned a WA6, not SE, and I would enjoy checking out the DT1990/WA6SE combination.

I agree that there are pros and cons to most any rig - especially at DV336 prices. I have no regrets about the purchase of this amp, I think it is one of the greatest audio bargains out there. I use my 336 in a 2nd (office) system and, for the couple of years that I have owned it, the amp has...

The rolling part is fine - I don't particularly like tying up my amp for 48 hours to get rid of hum. My other headphone rig doesn't require the run in so rolling is quick.

I've done that with all of my tubes but I think it is a PITA and I'd rather not. I have not brought myself to do the "Fitz" mod either.

I guess I've only used NOS tubes - I've had to resolve the hum with all that I've tried.

A couple of questions: Where did you purchase the adapters? Does this eliminate the hum that can be associated with 6sn7 tubes?

I have used, and loved, these tubes in my WA2

I think that the DT 1990s are excellent headphones. There are a vast number of SS and tube options, not to mention the countless combinations of components upstream. I am not able to make comparisons and would not consider discounting the opinions of others. What I am able to say is that I find...

I use my DT 1990 with a Woo Audio WA2 - they seem made for each other!

My opinion is certainly to be taken with a grain of salt but I'm happy to share what I think.

Glad it sounds good to you; I sure enjoy mine. What tubes were included?
