Krell KAV-150a Power Amplifier
Krell solid-state amplifier delivers 150W/300W with high-current design and dual mono power supply for authoritative speaker control in compact footprint.
I own Bliss Hifi, a high-end audio boutique and this Krell KAV-150a Solid State Amplifier is being listed as a trade in from one of my clients. It is in good condition with normal wear for its age and though it has never seen service, it still sounds great. The top cover has some discoloration from the heat the amp has put out over the years, but it looks much better in person than the pictures show.
Only the amplifier and a stock power cable are included. The original packaging is not available, but I will pack it securely to ensure safe transit and delivery to you..
Check my stellar feedback across online marketplaces and Google reviews and buy with confidence. This listing includes free insured shipping across the CONUS. I prefer fee-free payments, which include ACH bank payments, PayPal F&F, Venmo Gift, cashier’s check, and personal check (has to clear prior to shipping), but I can accept credit card payments through my QuickBooks invoicing system.
Happy to answer any questions. Thanks for your consideration.
More about the unit:
The Krell KAV-150a delivers the performance and build quality the brand is known for in a well-executed stereo design. Designed with both music and home theater applications in mind, this amplifier brings Krell’s high-current design philosophy to a more accessible price point. With 150 watts per channel into 8 ohms and doubling to 300 watts into 4 ohms, the KAV-150a demonstrates substantial power reserves and the current delivery capability needed to drive demanding speakers with authority. The Class A/B output stage and dual mono power supply design maintain clean, controlled sound with low distortion of just 0.06% THD at 1kHz.
What distinguishes the KAV-150a is its ability to deliver genuine high-end performance in a compact footprint. The balanced circuit topology with both RCA and XLR inputs provides versatility, while the bridging capability allows conversion to a 600-watt monoblock configuration for those seeking even greater power. The substantial transformer and carefully managed thermal design ensure stable operation during demanding passages, with a signal-to-noise ratio of 112dB maintaining a quiet background. Whether anchoring a two-channel music system or serving as part of a larger setup, the KAV-150a provides the grip and transparency that allow speakers to perform at their best, representing Krell’s engineering expertise in a practical package.
