SA20
There are two frequent problems with hi-fi amplifiers. Class A, the traditional audiophile’s choice, uses a single power supply constantly running at full capacity, even when there’s no signal coming through. Great for reproducing those subtle details at low levels however struggles to provide extreme power when needed.
Class A/B, the most common amp class, switches between the two internal amplifiers, one for each half of the waveform. Far more efficient but often a recipe for crossover distortion, since those low-level details we crave can get lost within any mis-match between the two switching over.
Class G is essentially a hybrid amplifier, utilising Class A specifically for low-level signals, but when required switching in an additional power supply to power those larger sections of the waveform.

Pathos Inpol 2
Pathos Inpol 2 – Integrated Amplifier
Is the latest creation from Pathos, so-called because in the design Pathos presents the 2nd generation of their proprietary INPOL® technology.
It is also a completely balanced dual-mono configuration – easily recognized by the styling.
INPOL®, which carries a worldwide patent and gave birth to the multi-award winning products TT and InPower, has undergone advanced evolution.
The INPOL2 is a unique amplifier in many aspects and its sound quality will simply astound.
InPol (Inseguitore Pompa Linear – Linear Pump Follower) is a system patented by Pathos Acoustics which has enjoyed great success and won many awards.
Inpol devices have a special sonic personality obtainable only by means of this particular circuit design – fully balanced in Class A using a single solid-state component in follower configuration, with high current gain and with voltage gain together. The valve amplifier amplifies the input signal voltage and InPol supplies the current to drive the loudspeakers without any further amplification. In this way, the signal is entrusted to the valves and becomes a true copy of the original, with all the quality, purity and harmonic content of the original.
This technology allows an increase in the theoretical output in pure Class A of between 25% and 50% together with a low output impedance which is fundamental for the damping factor and further improved by the double InPol.

LINE MAGNETIC LM-150IA
LM-150IA- Integrated Amplifier – Push Pull KT120 – 2x100W
Overview:
One hundred watts per channel, Class AB Integrated Stereo Amplifier with KT150 output power tubes, 12AX7, 12AU7 and 6SN7 input tubes. 12AX7, 12AU7 and 6SN7 are for three stages of signal amplification while KT150 for the power amplification.
Well selected and matched tubes. Tubes we chose are Shuguang 12AX7, Shuguang 12AU7, Electro Harmonix 6SN7 and Tung-sol KT150. No matter it is the Pre-stage or power stage of tubes we select and choose the best matching ones to use on the same unit of the amplifier to get the best sound quality out of it.
Different from other inputs Pre-In offers you a possibility to connect to some other Preamplifier so that you can the LM-150IA as a power amplifier.
User bias control has been used for bias adjustment including 2 vu-meters.
Specially designed Toroid transformers made of Z11 Core for power supply and two Japanese Audio grade EI types of output transformers with wide bandwidth are applied. All transformers and chokes are encapsulated and installed separately on the amplifier to avoid and lower the disturbance between each other.
Japanese ALPS volume potentiometer, American MIT and German Mcap coupling Capacitors etc Audio grade of components have been applied.
LINE MAGNETIC LM-513PA
LM-513PA – Mono Amplifier – Push Pull 845 – 1x160W (Price for a pair)
The mono amplifier LM-513PA is a Push-Pull amplifier with 4x 845 tubes in pure Class A amplification and delivers 1x160W. The use of high-quality components (Multicap, Philips BC filter, Motorola) hand-made construction with the finest point-to-point wiring for the most part is the guarantee of exemplary reliability.
Pathos Ethos
Pathos Ethos: Integrated amplifier (HiDac Optional)
The edged exterior of the Éthos does not provide any clues about how to control the amplifier. Like with the Logos to operate the Éthos is a hit and miss trial and error affair. Both recessed buttons on the front panel are difficult to access and they carry no marks or descriptions. The remote controller (by the way very elegant slick piece of metal) will not help a lot as it also has just anonymous buttons. Either a user looks into the amp’s manual or just presses something to see what it does. This is a kind of trade-off for the clean Italian design,
Other than that the Éthos is built with great attention to detail, the selection of parts, craftsmanship and internal layout scream with quality and care. I loved the amp’s heatsinks that are cast in the shape of Pathos’ logo.
The central part is occupied by a turquoise alphanumeric display that is dimmable. The power switch can be found at the rear panel and there is no need to power the amp off as it stays in a standby mode at idle, A ‘progress bar’ on the display will inform you that the Éthos is waking up – it takes no more than 30 seconds before all circuits are stabilized.
