Current retail price is $3500, including the $300 Jupiter coupling capacitor upgrade. I understand the price of this amp and certain other A&S amps will be increasing by 15% soon. - Class A single ended transformer coupled tube rectified zero feedback. Brief sonic description: harmonic richness, tonal density, bandwidth extension, immediacy, impact, and intimate listening position (sometimes as if you’re on stage with the performers) with authority and control over the drivers – overall, leans more engaging and emotional rather than analytical. - I am the original owner and took delivery of the amp in mid-January 2021. This is the current version with the latest Rev 2 updates. - This amp is a custom build with the Jupiter coupling capacitor upgrade (same ones used on the Bigger Ben and Nautilus) and no onboard volume control such that it effectively operates as a power amplifier (thus, a separate device with volume control such as a preamp, DAC, or level control is required for use). I had the amp built this way for flexibility and versatility for headphone and 2-channel listening with separate components. - Custom selectable single ended inputs with or without input transformer: - Input 1: with input transformer - Input 2: without input transformer - Includes Seahorse case, stock power cable, manual, and original packaging. - Includes stock tubes: JJ 5U4GB rectifier, Tung Sol 6L6GC STR power tubes, Tung Sol 6SL7 input tube. - Like-new condition with no blemishes. Non-smoking, no-pet household. **PAYMENT, SHIPPING, TRADES, ETC.** PayPal Friends and Family or other no fee transaction is preferred. Buyer pays for any PayPal fees and shipping cost from Los Angeles to Continental US (FedEx Ground, fully insured with signature). Free in-person pickup in Southern California subject to mutual agreement and payment via PayPal Friends and Family or other no fee transaction (since PayPal protections don’t apply to in-person pickup). No returns. Seller references available upon request. I am open to reasonable trade offers. **OPTIONAL ADD-ONS** ![IMG_20210515_162558__01](https://us1.discourse-cdn.com/flex016/uploads/headphones/original/3X/8/1/81980d21b7debefba0fae484960f8c914fae32b7.jpeg) ![IMG_20210515_162616__01](https://us1.discourse-cdn.com/flex016/uploads/headphones/original/3X/4/9/4954396feb1465429b4d513d428ec162b824f6f1.jpeg) Add-on custom built ampsandsound passive preamplifier ($100). Volume control, two selectable single ended inputs, and two single ended outputs. I found myself using the passive preamplifier for headphones, and a separate active preamplifier for loudspeakers. Add-on 9-pin to 8-pin adapter ($20). Made by Deyan on Head-Fi. [Deyan | Headphone Reviews and Discussion - Head-Fi.org](https://www.head-fi.org/members/deyan.515868/). I highly recommend using 9-pin tubes with the amp, which requires an adapter. In fact, multiple A&S amps are in the process of being updated to convert from an 8-pin input tube to a 9-pin input tube. Add-on tubes: Tung Sol 5AR4 ($20), Tung Sol 6550 ($40 for pair), JJ KT88 blue glass Slovak made ($115 for pair), NOS GE 6L6GC 1960s USA made ($135 for pair). Various 12A\_7 input tubes available upon request (requires 9-pin to 8-pin adapter). \*Each abovementioned tube has less than 200 hours of use and is new production non-USA made unless otherwise indicated. **SELECT REVIEWS/THREADS** > [@Ampsandsound Mogwai](https://forum.headphones.com/t/ampsandsound-mogwai/10087): > > I’m surprised I don’t see an official thread for the Mogwai model! Well I hope we can talk about it here. I sold most of my amps and am down to the Mogwai SE with upgraded Jupiter caps as my reference amp for my Zmf collection. I feel perfectly content with this one!
