Blue Circle Audio 2k4sh custom tube hybrid stereo power amplifier, 6SN7 + Class D, 300W/600W ch

Selling my Blue Circle Audio 2K4sh Custom power amplifier. This amp was
built in 2016 using the 300w/channel BCA 2K4sh hybrid tube and SS
platform. I am the second owner but have rated this as 9/10 since I purchased from the original owner and I've only used it for about 1 month.  This amp was customized at production by Gilbert Yeung to allow the user to adjust the amount of 6SN7 tube
gain and solid state gain to be blended on the input stage. The normal
2k4sh hybrid amp only allows the user to turn the tube circuit on/off and does
not allow the variable gain blend of this custom version. Delivers
300W/ch into 8ohm and 600W/ch into 4ohm. Balanced and RCA inputs, dual
speakers terminals.
Physically, the chassis is in excellent condition with no visually identifiable defects whatsoever. There may be some dust that shows in the photos. The sound of this amplifier can be viewed as seductive with a powerful and extended low end, warm and saturated mids and a smooth,
airy and extended high end. The imaging and sound stage are simply
superb in all aspects. As described above, the input stage is an
adjustable 6SN7 and SS configuration with a class D output stage. This
is NOT the class D amps of yesterday and sounds completely musical and
natural. It runs very cool, has a massively overbuilt power supply and
sounds equally good in casual listening as it does in critical sessions.
Inside views show extensive use of BC dampening compound. Even though
the top cover has provisions for fans there is no fan in this amp. I
will include a NOS GE 6SN7 tube that offers a notable improvement over
the stock EH tube.

The amp will be shipped double boxed and i can ship to Canada. My only reason for selling is I've decided to go with a custom set of monoblock amps (again with a custom tube input stage).
