If an Italian sound exists, I gather it isn’t an engineering spec but a sensibility. Where most gear aims to get out of the way of the music, boutique hi-fi from Italy participates in it. It isn’t neutral in the strictest sense. For many, it’s more human.Sonically, the 845s occupy their own terrain. They don’t punch like KT150s or dazzle with immediacy. Instead, they bloom. They stretch space, thicken tone, and draw you in with an unhurried, dimensional ease. They flesh out the harmonic body of a note and let its decay hang in the air without collapsing the structure around it. The Unison Reference amplifiers make full use of that character.Are they worth the price? How attached are you to your second kidney?When everything settles and the mind calms, what’s left is music: vivid, beautiful, whole, and rendered with uncommon care. The Unison Reference amplifiers turn spending into savoring, and savor them I did.

Here, the floating panel chassis design allows for maximum air flow, offering abundant cooling for the circuit boards and establishing stable air currents throughout. It also employs magnetically and capacitively optimized circuitry, using no ferro-magnetic materials, and implements galvanic isolation by using optical coupling.

The Schrödinger uses the Audionet Ultra Linear Amplifier technology to manage real-time linearization of distortions, is DC coupled, and its massive, gold-plated copper rails deliver the signal to the speaker terminals without loss. It uses two separate power supplies, one for device control and detection, and a second to monitor zero-crossing of mains power, the crucial point where the mains power alternating current signal transitions through the zero voltage level, from positive to negative or vice versa.

I was forewarned that my review sample was brand new and would need some running in, but that it would get on song relatively quickly. Before listening, I just switched it on and left it idling for several days.

For my initial listening impressions, I positioned the U-588 on an Artesania Organic Line Modular Floor Platform and connected it using a long Belden 19364 power cable. The Antipodes Oladra music server was used as a source, connected directly to the U-588 via Belden RG59 coax and simultaneously also via I2S to the LAiV uDDC and Harmony DAC. This way, I could test the Aavik’s analog preamp section and perform comparisons with its built-in DAC. Finally, to enable UPnP streaming via the network, I connected the U-588 via an Ethernet cable

The Mola Mola stack is much like milk and cookies – no one notices how good the milk is if the cookies suck. The Makua is definitely the cookies and it’s a great cookie. The Perca is the milk and matches it perfectly, elevating the combination. The Mola Mola gear seems to be tailored to work best together as a system and not as separates. You could match the Makua with other gear as I did and have success with that, but I didn’t feel that the other gear I had on hand brought out the best in the Mola Mola Perca. I think the Perca showcased the other flaws in the system, being a “garbage in, garbage out” endeavor in some ways. If you are amplifying an altered signal it’s going to be louder, but still altered and perhaps even worse than you realized. So this is a bit unfair for the Perca, but I think it showcases how critical it is to have a quality upstream signal. It also shows that the Mola Mola Perca is honest and not going to fix system problems for you. I think you can find other gear that would be a good match for the Perca, but you’d have to do some hunting finding gear that is clean and clear. So why would you when there’s already an option that was designed from the beginning to be this good?
