I was and am thrilled with the wonderful sound quality, quiet operation in my LSA integrated amplifier. They represent a distinct improvement over the China-sourced tubes included with the amplifier. Shipment was handled well, and I received the tubes in approximately 3 weeks, which strikes me as very good given the security regimes in postal mail between certain countries in Europe and Asia and the United Sates.
I intend to purchase a second pair in the next month "for the future," although the tubes will likely last many years.

1975 Reflektor ! Wow, compares well to the Siemens CCa and Amperex PQ.
They have real nice bass, extended treble, and are accurate..
I found the CCa to have a slightly more natural sound and extended treble, but
only after changing them out a few times.
These tubes easily beat my previous Philips miniwatt SQ ones. They have a very impressive soundstage with airy but detailed highs and mid, base is tight and poverfull.
