EMOTIVE AUDIO EPIFANIA REVIEW<\/h1>\n

The Emotive Audio\u00a0Epifania<\/em><\/strong> followed the Emotive Audio Sira-LE<\/a> in my system. The Sira-LE is a fantastic preamp, the Epifania is in another league.<\/p>\n

The Epifania is described by Emotive audio as being “fundamentally different from all of our previous linestage preamplifier designs.”<\/p>\n

If you learn more about the Epifania, the design considerations and the evolution from its stablemate the Sira, via the Sira-LE, you’ll come to know that Epifania designer Fred Voltz genuinely felt that there wasn’t a great deal of opportunity available to improve upon the performance of the Sira-LE. At least not without starting out from scratch.<\/p>\n

“The Epifania is fundamentally different from all of our previous linestage preamplifier designs. If you take a look at the rest of our web site, <\/span>http:\/\/www.emotiveaudio.com\/<\/a> you’ll see that the Poeta, Sira, and Sira-LE are all based on the same general design principle (just as were the Prima and Erato before them). All of our other designs have been based on two audio stages….<\/span>we were quite pleased with the Sira-LE and often wondered whether there was even much room for improvement at that link of the audio system chain. But, that wondering grew into desire. We really wanted to push the issue–to make a new level of performance where there hadn’t been one before. So, to some extent, we started over.”<\/p>\n

And start over they did. The Epifania boasts the same low output impedance as their Sira \/ Sira-LE (cathode follower designs), but elimantes a cathode follower from the circuit topology altogether. A\u00a0single hybrid audio stage was developed for the Epifania where the audio signal passes through only one tube en route to the power amplifier.<\/p>\n

Significant improvements to the power supply include the elimination of all electrolytic capacitors from the high voltage supply, replaced by smaller value oil filled capacitors and a large choke, for DC filtering. The filtered DC is then current regulated for each channel before being voltage regulated with gas filled regulator tubes. The design takes special care with the heater supply for the audio tubes which is filtered with a large input choke followed by quality filter capacitors.<\/p>\n

The voltage regulator tubes are an unusual presence in the Epifania design. For one thing, you won’t need to obsess over finding expensive NOS replacements for these tubes, as there essentially are none. Furthermore, you can replace these easily for less than $10 each. I picked up replacements from Brent Jesse <\/a>for only six bucks a pop.<\/p>\n

The star of the tube lineup in the Emotive Audio Epifania is the\u00a0Sophia Electric 274B. I read somewhere that a RCA 5R4GY is a better performer, so I ordered a\u00a0WWII version of the military RCA 5R4GY brownbase dual bottom getter, a superb rectifier tube supplied by Brent Jesse for $200<\/span><\/span><\/p>\n

The parts quality of the Epifania <\/em>is super high. The chassis is constructed from very thick (0.1 inch) stainless steel and beautiful maple wood. It uses a custom potted power transformer along with Yamamoto machined Teflon tube sockets, throughout. The RCA audio connectors are all WBT Topline.<\/p>\n
