"...Thank you for your message. As you know, tubes in general need to settle-in to the new environment, and get better with 'burn-in'. With the Siemens Halske E188CC and E88CC you are going to hear ALL the frequencies passing through your system, the more sensitive the tube the more you will hear. You are using AUDIO GRADE tubes with the Siemens E188CC, which have a sonic-signature that reproduces not only the 'odd'harmonics (1-3-5 etc.) but also the 'even' harmonics (2-4-6 etc.) The new tubes made today in China and Russia only reproduce 'odd' harmonics - thats why everyone upgrades to a vintage made tube made decades ago when these rare 'earth-metals' were available in the inner construction of the vintage tube - now these metals are too expensive to use and todays tube-makers have found cheaper substitutes which seem to work but do not reproduce all the nuances and textures in music. ..."

"Dear TYube Museum,

Hi, The pair of (E188CC tubes) arrived an hour ago and I wasted no time. It is exactly what you have recommended. The pair makes my Bitfrost/Lyr/LCD-02 sings ! I like em more than the 70s 6922 Mullard on LCD-2. Haven't tried with the other brighter cans; HD-800 & 700. I love them.

Thank you.
