SB90T hybrid stereo power amplifier
If you want a taste of what Blue Circle hybrid power amplifier sound is like in an entry level unit then SB90T is the amp for you. Its power output is 90 watts per channel and its 3.5" high chassis allows it to be mounted on a well-ventilated shelf. It provides lots of wallop in a small package.

$3515.00BC202 hybrid stereo power amplifier
The BC202 outputs 125 watts into 8 ohms and 200 watts into 4 ohms per channel. It is a true balanced design from input to output with both positive and negative binding posts being "hot" with signal.The DC-coupled output stages local "on board" filtering capacitor is located less than an inch away from the actual output devices for better transient response. All control circuits are built in the analog domain. This means that no digital clock is used to otherwise contaminate the analog signal's sonic integrity. After all, this IS an analog amplifier not a digital amplifier.
The BC202 includes a heavy gauge power supply and a grounded return path for both the tube and output stages with the exact same reference for both tube and output stages to yield the best matching performance. A 20 Amp Neutrik "Power Con" power connector with 6ft hospital grade 14 awg power cord is standard equipment for optimum transference of A/C power. Longer lengths available.
All internal A/C power is controlled by 30A A/C power relays to provid the shortest A/C power run inside the chassis to minimize noise. Over 200,000uF in power supply filtering so you'll have no shortage of power to pump through your speakers when the music demands is. Various faceplate, base and cover colors are available options.

$8245.00BC204 hybrid stereo power amplifier
The BC204 is the smaller brother of the BC206. At 150 watts of high bias Class AB per channel the BC204 has almost everything its sibling the BC206 has.
Like the BC206, it uses a total of three power output modules per channel. It also has separate output, input tube stage and control power supplies and even the AC mains plug is the same as the BC206. At only 30 watts/channel less than the BC206, it's almost a BC206 in a smaller package!
Various faceplate, cover and base options are available.

$11,695.00BC206 hybrid stereo power amplifier
This is the biggest stereo power amp from Blue Circle, at 180 watts high bias Class AB per channel.
It features: Blue Circle Audio True Balanced Output Technology, custom-designed ultra high-speed power supply filter capacitors in the high/low voltage supply, isolated power supply for the tube input stage, solid-state output stage and the control circuit has it own power transformer for total separation from the signal path. The A/C mains Neutrik PowerCon is the ulitmate A/C power transfer connection. Various faceplate, cover and base options are available.

$16,495.00NSL stereo power amplifier
The NSL is a 28 watts per channel, stereo, solid state, almost Class B, ultra-low distortion, power amplifier. What's up with Blue Circle and TLP Audio offering a 28 watt per channel amplifier?
Accuracy
If you know anything about Blue Circle products, you know that it's ALWAYS about the the music. In order to accurately reproduce good music, an amplifier must be "accurate" and accurate means low distortion. Blue Circle defines accuracy and low distortion as sound passing through the amplifier without alteration. "Almost Class B" means that the amp fine-tuned to keep noise out and keep it running cool.The NSL Redefines Powerful
The NSL has a measured output of 28 watts per channel into 8 ohms and 56 watts into 4 ohms per channel. The NSL's power output numbers are not a reflection of just how good it sounds. It also has an output impedance lower than most 300 watt power amplifiers. Instead of using a few large transistors, like typical amp designs, Blue Circle parallels 288 op amps at the output stage. This is like using multiple smaller capacitors in the power supply instead of one big capacitor to obtain faster and smoother response.In power output stage terms, the NSL can get the output impedance lower than ever before. This yields much better control of the speaker drivers (high damping factor) and as a result this amp sounds more powerful than power amps with many times the output wattage of the NSL.
Very Low Noise
Because of the parallel op-amp design, the NSL has less noise than headphone amps. The residual noise is lower than human hearing can detect therefore maximizing musical detail and widening the sound stage.Battery Operation
Since the NSL can run on batteries, it's noise floor can go even lower. It uses two 115Ah 12V deep cycle batteries, and it will run up to 24 hours with one charge.Expandable
The output stage of the NSL is a modular design, more output modules can be added to increase power output. It is possible to have the NSL output increased to over 500 watts into 0.5 ohms.The Sound
Simply put, if it didn't sound good, we wouldn't be telling you about it because Blue Circle wouldn’t be producing it.Technical specs

$19,500.00BC208 Hybrid Class AB full balanced mono power amplifier w/6922 input
The BC208 may look like a mono version of the BC206 but it's not. They are quite different. The '208 does not follow the traditional rules of amplifier design and we don't expect that it will appeal to everyone.
The difference between the BC208 and the other '200' series amplifiers is that it is a low gain high power amplifier. In fact it has the lowest voltage gain of any Blue Circle amplifier ever produced. With a low gain amplifier the preamplifier needs to produce a higher signal in order to get the same amount of power that you would get from a more conventional high gain amplifier. This approach is somewhat nontraditional but it results in a higher system signal-to-noise ratio yielding a quieter background, clearer image and more vivid focus.
Various faceplate, cover and base options are available.
