DEQX A250x3 (Tri-amp) Power Amplifier I am looking to sell 2 x DEQX A250x3 (Tri-amp) amplifiers. The price listed is for the pair and not individually. For a full description go onto the DEQX website and look under legacy products. These are being used to drive the VAF I-66 floor standers. Even with how light and small they are, there is no issue driving those speakers in active mode. Hypex amplifier modules are used. I am selling these as I am trying to sell a DEQX HDP-4 processor that is used as the crossover and will not need these afterwards. It will be easier to sell to someone in Adela
