Hi to the community....
I just received the Cavalli, and immediately swapped out the standard 6922 for a 1964 Siemens NOS. I have a question, after burning the tube in for 40+ hours and connecting a pair of AKG IEM's with a 6.5mm adapter, the sound comes out like its underwater. i swapped out usb cable and I swapped out IEM to a pair of Klipsch IEM's, same thing. But I went i pulled my first gen BOSE noice cancellers out of the closet and BAM...clear as day.
Are the IEMs being over driven?
Thanks for this community, the Senns 6xx are dropping for me in August and I dont want to go through with that.
The Siemens tubes I am guessing it is a E88CC can be very airy and somewhat analytical.. If you want a warmer sound I would suggest with out the airy distant sound. Try a Amperex 6922 or 7308.
Thanks for the reply...as the story goes, the 1964 Seimens 6922 has a great soundstage...but it makes the IEMs sound like they are under water. Driving the Gen1 Bose Noise Cancelling headphones...smooth as silk. I think the IEMs have a weird ohm setting so they work with smartphones.
just my guess...Also, I had bought them through audiotubes.com, and he bench tests every single tube that leaves his place...in fact he had a matched pair.
I still think the IEMs are being over driven...but oh well, I have ordered the Senn 6xx...so we shall see.
Thanks for the reply
