The Mogwai SE Rev 2 - ampsandsound is a high powered and versatile headphone and loudspeaker tube amplifier.
- Price: SOLD. 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.

OPTIONAL ADD-ONS
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. 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.
