The rarely available Audire Tenendo. These came two ways, one with normal gain and the other with low gain and this is the low gain model. That makes it great for horn speakers as there is much less hiss, or if your preamp has a good amount of gain, you can enjoy it with all speakers. My preamp is only about 10-12db of gain, so I sometimes was wide open on the volume. Nice open soundstage and a really free sound with expressive highs and good transparency. Several small scratches on the lid and a few others, but decent. No original box or manual, so I will pack it safely and insure it.
