It has been some time now since I posted my initial impressions of this new hybrid amplifier from Head-Direct.
After considerable listening, and changing opamps to try to best match with the cleartop RCA tube, I have come to the conclusion that this is one of the best-sounding amps that I have owned.
I feel that the EF1 lacks the recognition that it clearly deserves, most likely due to the fact that Head-Direct is a small company that is often overlooked when shopping for a quality amp.
I finally selected my one remaining set of AD743 opamps for use in my EF1, and they sound absolutely stunning in all respects. I have paired the EF1 with all of my phones, and it performs equally well with each, driving them effortlessly regardless of the impedance or sensitivity of the phones.
Head-Direct graciously offers a 30 day refund if not happy, so there is no risk involved in auditioning this fine amp.
I don't wish to come across as a shill for Head-Direct, but I do like to give credit where due in this crowded segment of the audio marketplace, and in this case, the EF1 certainly deserves credit for its fine overall tonal accuracy, soundstage and sense of realism.
