Marantz HD-AMP1 review
This unit delivers 20W/8 Ohms of power vs 35/8 from his Marantz opponent. The device is made on a two-layer chassis with an additional bottom plate, which effectively dampens any mechanical vibration that can degrade the sound. The HD-AMP1 is the first Marantz model in this class to use pulsed amplification technology. The company's specialists for a long time radiated class D circuitry, setting themselves the goal of achieving with its help sound quality that meets Marantz's high standards. As a result, using proprietary HDAM modules and a specially calculated common current feedback, it was possible to create a class D apparatus. 
Marantz PM8005 review
The amplifier is equipped with a tri-band tone control (bass, midrange, treble), which greatly simplifies the setting of the optimal tonal balance depending on the characteristics of other components of the system and listening room. On the rear panel of the Marantz PM8005 there are five line inputs, an input for connecting an MM-cartridge of a vinyl disc player, an output for a recording device. The amplifier is equipped with convenient proprietary SPKR-100 terminals for connecting speakers whose impedance can be in the range from 4 to 16 Ohms. You can also connect headphones with a 6.3 mm diameter jack to the Marantz PM8005. 
Marantz HD-AMP1 pros & cons
Pros
- Build quality seems to be right on for something at this level
- The sound is truly riveting across all genres
Cons
- I wish ergonomics was better thought out
Marantz PM8005 pros & cons
Pros
- The uniqueness lies in the work with current feedback, which allows you to generate a large supply of energy
- In order to eliminate unnecessary vibrations, the manufacturer created a special three-layer system
Cons
- As for me, it is too heavy
