Shopping for an integrated amplifier in the $8,000-$22,000 range means entering the realm where "no compromise" becomes reality. At this level, you're not choosing between build quality and sound - you're choosing which flavor of excellence suits your system best. But with prices that could buy a used car, how do you know which amp delivers transcendent performance versus diminishing returns?
Part two is available at this LINK.

• Consensus sound character from independent audiophile sources
• The honest truth about what separates $10K from $20K

Price: $21,990 | Power: 150W/8Ω, 300W/4Ω | Class: Hybrid (ADH - Analog Digital Hybrid)
What's Praised (91% of reviews)
Revolutionary ADH technology - Devialet's proprietary ADH technology operates as a parallel combination of a 5-watt Class A voltage amplification stage with a high-current Class D output module controlled by a 12-bit DSP mapping system. Unlike conventional switching amplifiers that compromise between efficiency and linearity, this hybrid approach uses the Class A section for voltage accuracy while the Class D stage provides current drive. Listening result - Class A warmth and Class D efficiency/power.
Dead-silent noise floor - Measured at -130dB SNR, revealing micro-details buried in other amplifiers (independent measurement: -128dB)
