**For Sale: Neurochrome 686 Power Amplifier with Custom Bigbottle Audio Linear Power Supply**
Owned from new and kept in a smoke free/pet free environment.
This is one of those setups I never thought I’d part with. It is the best amplifier I have ever experienced in my system. Sadly future domestic arrangements dictate its release to another appreciative owner.
The Neurochrome 686 is simply stunning—clean, powerful, and effortlessly transparent. It’s the kind of amp that disappears and lets the music speak. Every detail, every breath, every subtle texture comes through with incredible clarity. But what really takes it to the next level is the custom linear power supply, hand-built by Bigbottle Audio. It’s not just an upgrade—it transforms the amp into something truly special.
The PSU delivers beautifully clean power, lowering the noise floor and tightening the bass. Vocals feel more lifelike, instruments more dimensional. It’s the kind of synergy that makes you sit back and rediscover your favourite albums all over again.
I’ve used this combo in a dedicated listening setup, and it’s never missed a beat. Built with care, housed in solid enclosures, and finished to a high standard. It’s ready to slot into any serious system.
**Details:**
- Neurochrome 686: 180W per channel into 8Ω, ultra-low distortion, reference-grade transparency
- Wired with SAEC triple C
-Solid Copper RCA inputs and outputs
- Bigbottle Audio PSU: Custom linear design, premium components, dead silent operation
- Condition: Excellent, lightly used
- Location: Nantwich South Cheshire
- Price: £1800
- Shipping: Available at buyer’s expense, collection welcome. Or will deliver within a reasonable driving time of South Cheshire
If you’re looking for an amp that genuinely elevates your system—something that brings music to life with honesty and emotion—this is it.
Happy to answer any questions.
