OAD Ultrafidelity Vajra Power Amplifier
Made in Melbourne, this is one highly refined power amplifier. John De Sensi has been making electronics for decades previously under the Music Labs brand name. We sold the the Music Labs gear a long time ago but this is a lot better than that.
Firstly the case work is expertly machined and has a high end luxury feel that isn't present in any other Australian manufactured equipment. The sound is also tighter, more detailed and refined. And that's all down to a lower noise floor.
We think that this pre and power combination are actually their European counterparts a run for their money.
On display now at Carlton Audio Visual.
