A bad boy:

I have the MrSpeakers Ether CX (Closed). Sounds pretty good, detailed, they are light and isolate quite a bit from ambient noise but I think they are very overrated. I prefer the Audeze LCD-XC although they are terribly heavier (and expensive)

Happy Birthday !!

Nice phono preamp ?

Where I live there are quite a few owls ... bad place for small animals and even cats.

Something funny

Happy Birthday!

The album is simply spectacular. I really liked "September Second"

Added "Hemispheres" to my playlist. Thanks Mikey

Am I the only one who uses 450Vdc output?

I have been focusing on gain tubes. I've been alternating the E80CC, E180CC, 6189 ... and I think the E180CC (Mullard/Philips) is the one with the best balance (quality vs. gain level). I liked the E80CC a lot but the gain increase was minimal compared to 12AU7. For the driver's tubes, I've been using ECC803S and several "esoteric" 12AX7 for a while, but I opted for the modest ECC83 Svetlana "Winged C" and a pair of Mullard CV4004 with unknown mileage too. IMO the most critical here are the gain tubes so I have not wasted much time here. As for the "Jiml/Gilmore" modification to raise the current to the plate of the driver tube, I think it was a good upgrade (thanks to both of you and Mwl for sharing it). If I'm not wrong, only Michael and I did the mod?

Has anyone continued to investigate something about preamp tubes? I still use the E180CC instead of the 12AU7.

Happy Birthday!!!

I forgot to comment that the German-Maestro also have identical Beyer housings and I would swear they also use the same drivers. I have several German_Maestro at home and they are very similar to their Beyer counterparts. German-Maestro webside

I think that Michael and I talked about that project at that time and decided to put our attention to the T2 mini. I don't remember how the two Sandwich prototypes ended. Maybe Congo or Matt can tell us something.

Umm.. here ? Ah no, sorry I´m mistake. it´s a Superlux.

In pharma-industry here in Europe are usually 10 to 11 years. In the US they are somewhat longer I think 20 in some cases. Far from this, the DT770 has been in production for more than 20 years so it would not surprise me if its design patent is expired or that Behringer and Beyer share shareholding. Something that catches my attention is that the new model is called "DT330/DT660" which would lead to suppose that it is a model "inferior" to the DT770.

jajajaja I settle for drugs and rock. Right now I don´t want sex ... it hurts too much ?

You need a Megatron ... and you know it.

I'm not sure. The same happens with the imitations of the "Beast". Although the driver is different, they are copying an industrial design. Another matter is that Beyer, after 1000 years of manufacturing the DT770, has granted or sold the patent.
