Home base or transportable, compact, headphone amp and linear DC wall plug. The wall plug is 12V 800mA and is well filtered. Based on two high performance amplifier chips (dual mono). The chips can deliver upto 10W into eight ohms. Here they are only required to deliver low power for headphones. Chips (TDA1905) are rated 0.1% THD at 3W.
Enclosure is ABS and lined top and bottom with heavy bituminised Al and earthed to form a ground plane and shielding. This makes the amp impervious to EMI/RFI from external devices and damps resonances and vibrations. 6.5mm phone jacks front and back - back is input - with volume control and antique knob. A front LED indicates on. Push button on/off switch at back.
Components are a mix of LESR NP caps and electrolytic caps. Resistors are carbon and metal film. The sound is very detailed against a black background. There is plenty of drive and bass goes very deep. Gain is high and should drive difficult HPs.
I will post of this price.
The item being advertised is sold "as is", and no warranty should be assumed unless otherwise indicated and agreed between the Buyer and the Seller. Photos representing the item being advertised form part of the description unless otherwise specified.
The search results reference several products with "Immerse" or related names—including Flare Audio Immerse ear inserts, Steven Slate VSX Immersion One headphones, and Earstraws immerse ear technology—but none of these match the specific product you're asking about. The Audma Brioso PHPA1 and iFi GO Blu are the only portable headphone amplifiers discussed in detail, and neither appears to be a "retro-thermionic" design.
To provide you with accurate information, I would need search results that specifically cover the "retro-thermionic Immerse" amplifier or a clarification about the correct product name. If you meant a different product, please let me know and I can help summarize community feedback based on available sources.
While the search results include a brief mention of a retro-thermionic preamp (the Icon CV-181 Z) that sold for $1,070 USD without tubes, this does not provide sufficient information to estimate pricing for the Immerse model. The search results lack:
- Specific listings or pricing data for the retro-thermionic Immerse headphone amplifier
- Current AUD pricing from retailers or secondhand markets
- Technical specifications that would inform fair market valuation
- Comparable models with established price points
To obtain an accurate AUD market estimate, you would need to:
- Check current Australian audio retailer listings and websites
- Review secondhand marketplaces for recent sales of this model
- Compare specifications and condition against similar compact headphone amplifiers in the Australian market
- Account for import duties or regional pricing variations if the product is sourced internationally
If you can provide additional details about the product's specifications or current listings you've found, I may be able to offer more contextual pricing guidance.
