TH300  

• Positioning: The entry-level design, focused on affordability and a compact footprint.  
• Description: Uses a basic circuit design that delivers clear audio performance for smaller rooms and straightforward setups. Offers the essential features needed for everyday listening, especially when compared to the more intricate circuitry and extra connectivity found in the TH350 and TH400 models, with the TH10-TH12 series adding even broader functionality.  

TH350  

• Positioning: The mid-range option aimed at a balance of performance and value.  
• Description: Incorporates a more robust power supply and refined analog design, making it a solid choice for larger environments and a step up from entry-level needs. Improves on the simpler setup of the TH300 while remaining less complex and costly than the TH400 and TH10-TH12 series.

TH400  

• Positioning: The high-end amplifier offering refined circuitry and enhanced audio performance.  
• Description: Employs improved noise reduction and precise signal handling suited for advanced listening setups and larger spaces. Stands apart from the TH350 and TH300 with superior circuit refinement, yet does not reach the comprehensive digital control and connectivity of the flagship TH10-TH12 series.

TH10-TH12  

• Positioning: The flagship integrated series focused on comprehensive connectivity and versatile performance.  
• Description: Features state-of-the-art digital control and broader connectivity options, making it suitable for both home theaters and high-end listening systems. Exceeds the performance and functional scope of the TH400, TH350, and TH300 by offering extra integration features.
