If you are looking for amplifiers that have a distinct sound that is ever present on every recording you play, the JC1+ amplifiers aren’t for you. They are just truth tellers plain and simple and these are the highest fidelity amplifiers I have ever had in my system. I find it hard to express all of the ways the JC1+ amplifiers elevated the sound of my system. What I can tell you is that I was sad on my last night of listening to the review pair and having to power them down in preparation for boxing them up and shipping them back to Parasound. I decided that I didn’t want to be without the JC1+ amplifiers in my system, so I purchased a new pair. That is the highest compliment I can give the JC1+ amplifiers.

So do you use the EI 30A? Just plug in an outlet, and plug the power strip for your system into the female plug for the EI 30A. I didn’t have room for the EI 30A to be close to my system, so I got a 12 ga extension cord to make the connection to the power strip. Marshall did warn me that switching-power supplies do not work well with balanced power, so I plugged the Pass B1 Korg Preamp wall wart directly into the outlet. To evaluate the EI 30A I used the Mullard 3-3 amp paired with the Korg B1 preamp.

Listening to the Terry Audio EI 30A with my system, I realized I have been thinking about power supplies all wrong. I always considered them as an accessory. The EI 30A made such a dramatic change in my system, that I consider it as a component just as valuable as an amplifier or a DAC. If you are looking to upgrade your entire system without changing its personality, you might want to check out the EI-30A.

Maybe times have changed. Perhaps we audio nuts don’t have as much of a bias against “newer” technology such as class D amplification and all of the advantages it can offer. Whatever the case, the Orchard Audio Starkrimson Mono Premium amplifiers never called attention to themselves in such a way that I ever worried about them being class D. In fact, it rarely even crossed my mind. I was just so involved in listening that nothing else really mattered, and that’s about the best one can expect from a really good stereo setup. And the other advantages? Well, moving the Pass Labs X250.8 from one side of my room to the other was a task, not that I really minded. But handling the little Starkrimson amps was nothing- each could be balanced easily in the palm of my hand. I will give the Pass Labs amp points for running a bit warm though, as my listening space tends a tad cool for comfort in the winter. Ask me again next summer, and I’m sure I’ll tell you a different story.

Up top, the REX 300 managed that balancing trick of sounding both detailed and sweet in the highs, with—I hope I’m not boring you here—excellent resolution of textures and harmonics. Flipping over to another Hip album, Road Apples (LP, MCA 3844804), Johnny Fay’s cymbals—both hi-hat and ride—are beautifully recorded. On “Little Bones,” I was drawn into the mix, bouncing off each instrument in turn. Those cymbals were prominent and juicy, and I could fall into them or let them recede back in my focus at will. I could also turn up the system really, really loud without any ear strain. On the contrary, the REX 300’s silky highs, redolent with crisp clarity in the fundamental and burnished richness in the harmonics, seemed to make loud listening sessions—especially to a magnificent album like Road Apples—a true pleasure.
