Do you think that there is enough space above the tube tops? Where does the heat go?Got socket savers for all tubes and running GEC KT66 for the very first time of this brand new pair. Will be back next month for impressions.
Given their price, I would hate to see the life of those wonderful tubes shortened by operating in high ambient temperatures.
I did not intend sarcasm.
). At the low-Z end of the hp spectrum, the Audeze LCD-X were at their level best. I am waiting for a custom SE amp-termination cable for the Clear and the Gjallarhorn (same 3.5mm termination) - what I have has XLR amp-termination. I cannot wait since the Gjallarhorn is still my favourite “overall” headphone. I will post.
I am relieved and pleased with the perceived outperformance of headphones in the “low” impedance setting. First, it is consistent with my experience with other amplifiers that have low output impedance: LP and Violectric V280. (The Woo WA3 as an OTL h/p/a is a ‘special situation’: I would use only high-Z h/p.) Second, I really did not want to have to frequently open up the amp to adjust the Z when switching h/p. Onto the Sophia EL34s: finesse with force, panache with power...not a huge step up from the Genalex KT77...enough to give notice that the music is being faithfully served...Awesome! Very cool and interesting in regards to your impressions of the headphone output settings, really good to know! I'm also glad to hear the Sophias are working out so well! Would you say they are way beyond the KT77s overall, just a few steps above, or on par, but just different?
For sure, let us all know how it continues to go with the Clears/Gjallarhorns as well as the tube break-in!
To @Effusion and @UntilThen: I have been extending my sessions with the TU-8200R now fitted with the Sophia Electric EL34s. I let the system run for close to five hours on CD repeat before donning the ZMF Auteur...to bathe in the most engaging, most enthralling, most involving, most realistic (in a headphone context) sound that I have encountered. All the usual audiophile parametres and sub-categories were evident but it was the gestalt that thrilled me the most. I did actually compare the “low” versus “high” impedance setting. I am keeping it at “low”: the high-Z Auteur, DT1770, and HD600 all were more communicative to me at the “low” versus “high” impedance setting. There was more “there” there (
Not true. No speakers need to be attached. If you have speakers attached and you plug in your headphone jack then the speakers will be cut out.
