What tubes are recommended for HD650's? Also, does the Lyr play well with the DT880?

To my ears, the Amperex Orange Globes ('66-69) and Amperex orange A-frames ('70-75) sound great with the 650. They are very detailed and smooth, but a little more forward and compliment the HD650's laidback sound very well.

 

I recently auditioned some '67 RTC E188CC's. Although costly, they pair extremely well and are probably endgame tubes for the HD650, IMO.

 

Not sure about the Beyer DT880 as I haven't heard it.

Sweet, I'll look at them. I've also been recommended the Bugle Boys.

+1. I was listening to the A-frames last night. Just OK with HD800 and LCD-3. But very, very nice and lush with the HD650. A great match. Didn't listen with the DT880 - ill do that later tonight and report back.

Are those A frames the ECC88 PQ shield ones? That's what i'm using at the moment, Heerlen made, best tubes i've heard so far with my hifimans, just wish i could find a back-up pair just as cheap.

 

The codes on my tubes are:

 

CAE

Δ2J1

 

So would that be '62 or '72? i have no idea how to tell what decade the tubes are from.

Those should be from '72. I have never seen an a-frame from the '60's.

 

Cool thing is the A-frames are less microphonic due to the sturdy A-frame construction.

I stand corrected. According to this guide I found, it looks like the first a-frame came out in '69.

 

Note: I'm not the author of this guide, I just found it linked somewhere and saved it. Apologies to whoever took the time to put it together.

I listened to the Amperex A-Frames with the Beyer DT880 (600 ohm). The mid-high and high frequencies are a little edgy and the sound is a bit congested; not bad per se, but not a great match. Pleasant, but both the phones and tubes can perform much better. I suspect that tubes with a warmer signature, like Mullards, would be a better match for the DT880. It seems like the idiosyncrasies of the Senn HD650 happen to line up well with the A-Frame tube. Warm, lush; very musical and engaging.
