    Upgrade from NAD 3020i

    I have used a NAD 3020i as my amp the latest 10 years. I have not found any amp that can match its details and treble. Though, since trying a NAD 319 dedicated power amp in my system I realise that the 3020i lacks definition and power in the lower frequencies. I wonder if anyone has a...

    How to increase power (MCS 3245 to 3275)

    I recently went to service an MCS 3245-10 I bought. (45 watt per channel) Upon initial dim-bulb turn on, it was idling fully lit. After disconnecting things, I found that the power transformer was shorted and pulling 110W by itself. None were available, so I bought a transformer for a 3275 (75...

    headphone upgrade

    So I had a thought. was looking on e-bay and found a bunch of Pioneer se-205 and 305 for cheap. Then I found that I could also buy the drivers from a set of Sony WH-1000XM4 for around $10 per side. so $20ish plus shipping. Is this a dumb idea? Is it even doable? The Pioneer's have 45mm drivers...
