The price is for one brand-new standard unit (without headphone function) of the Sophia Electric Baby II single-ended amplifier with USA voltage power transformer, which comes with a 180-day warranty from Sophia Electric. The Sophia Electric Single-Ended Integrated Baby Amplifier delivers 5 watts per channel (x2) of glorious, lush, magical sound with exceptional bandwidth, resolution, and dynamics. It is more powerful than typical 2A3 single-ended amplifiers. This amplifier can easily drive Sophia Electric Model One (88 dB) and Model Two (88 dB) speakers beautifully in a typical home or office setting.Retail Price: $1,299.99An optional headphone amplifier function is available as a custom order for an additional $399.99, perfect for high-impedance headphones like the HD600, HD650, and Hifiman HE600, as well as low-impedance models like the Grado 125, Philips 9500, and Sony headphones. All of the mentioned headphone models have been tested, and other headphones with similar impedance characteristics should work equally well.This single-ended Baby headphone amplifier features a transformer output, providing sonic performance that is light-years ahead of entry-level headphone amplifiers without transformer outputs.Since 2001, the Sophia Electric Baby Amplifier has established a track record for audiophile sonic performance and superior reliability. This new single-ended Baby amplifier is expected to continue that legacy as a standout performer.Shipping Carrier: FedEx, UPS, or USPS. Email us your shipping address, and we will find the most affordable shipping method for you.User Experiences:The Baby II amplifier arrived safely. It sounds great right out of the box with my Klipsch RP-600M speakers, which have a sensitivity rating of 96 dB. I’ve logged about 20 hours of listening so far. In comparison to my Decware Mini Torii Stereo Integrated Amp, I feel that the Sophia Electric Baby II amplifier offers a wider soundstage, better clarity, balance, and musicality.Happy customer Daniel from WashingtonSue,Thank you for the delivery of the Baby II, its great! The amp pairs perfectly with my vintage Klipsch Heresys in my garage/shop, and Im really, really happy. As expected with the Klipsch Heresys and a SET amp, the mids and highs are clear as a bell, but what is shocking is the bass is rich, punchy, and not weak at all!Thanks again for the great customer service.Garth BernsteinFrom Audiogon Forum:Link: https://forum.audiogon.com/discussions/my-experience-with-sophia-electric-baby-ii-amplifierJust to share some experience with you allWonderful little amp. Little as the rating 5-watt, but the amp is as heavy as many tube amps and sounds strong as at least 20-watt amp. When connected to my 86dB speakers, it sounds a lot louder than its rating of 5-watt, great dynamics.Initially, I was looking for a good sounding pre-owned single ended triode tube amp (under $1K) that I can listen to music while doing things around the house. I have a two other single-ended tube amps, I really love them but the tubes are expensive to replace, so a search for a good sounding tube amp that is under $1K and preferred with normal tubes as (EL34, KT88, 6550 or 5881) began. Not much found (!).Then I came across the Sophia Electric Baby II (5-watt) and the original Baby amp (push-pull 10-watt), both in used market, almost at the same price. Many good reviews on the original Baby but not much for the Baby II, so I was skeptical about the single-ended version (Baby II).Finally, I contacted Sophia Electric for information about the tubes, input: 6J1 (x2), output: 6P1T(x2). For those of you that are tube experts, there must be some equivalents?Anyway, I bought a used Baby II...After a few days in use, I found that it has the quality of those much more expensive SET amps, the beautiful mid-range, 3D image, great soundstage and very well controlled bass (even driving the small monitor type speakers). I have KEF Q150 and some single-driver speakers. The tubes it uses are not expensive as many other SET amps, but they can not be substituted as I was told. All credits to the well designed output transformers. The amp is very musical and good enough in the main system for serious listening. Mine doesnt have the headphone option, but I would not use this quality sounding amp just for headphone.I am using Cullen power cord, Canare 4S11 speaker cables, Canare interconnects and digital cable with Onkyo CD player and Schiit multibit DAC. Not much special equipment here, but for acoustic Jazz and Classical music that I listen to, musical is the only word I can think of. This is not the vintage tube sounding amp, this is very transparent with sweet mid-range of what single-ended amp is.Audiogon Forum user: francescalqby Ebay User Id: vintage_audio_guyFantastic Bargain - True High End SoundAs I write this review I am listening to music with the Baby II. If your speakers can go with the watts this amp is superior to any 2A3 or 300b amp near its modest price. Incredible soundstage beyond the speakers and far back behind. Piano has that ring you just dont hear unless its in the room. You wont regret this purchase. I am extremely satisfied.
