Triode Wire Labs or NRG Custom The Five for my 300b SET tube amp?


So currently, my Cayin HA-300 300b SET tube amp is powered by the Morrow Audio MAP3 power cable, which I think is quite a good cable with a smooth, neutral sound fairly wide soundstage and very nice vocals and detail. I listen mostly on my LCD-3 headphones and my DAC is the Chord Hugo TT2. I also have the Western Electric 300b and Sylvania 6SN7W metal base tubes on the HA-300.

What I'd like is a bit more dynamic punch and meat without sacrificing resolution and soundstage, as well as not going too warm or too cold.

So I'm looking at two power cables, the Triode Wire Plus Seven Plus or the NRG Custom The Five. Also, is there a good reason to go with the Ten Plus or The One since the 300b tube amp?

@jambaj0e yes the Seven Plus is very good. Not surprised at all you like it. Very open and dynamic. Enjoy!

@audphile1 Yeah! I'm just so surprised how much better it is! It's almost like I just changed my headphones or took out some cotton from the earcups or something, lol.

The crazy thing is while I don't think soundstage got bigger, instrument separation became clearer and more distinct, especially with how the drums sound.

Shoot, now I'm so tempted to upgrade my XLR from my Morrow Audio MA4 cables. They do have the Furutech CF-601M/CF-602F Rhodium connectors, though. Can I use them on a new cable?

By the way, if you guys want to hear something absolutely sublime, have a listen to "Space Lion" by Tank from the Cowboy Bebop Soundtrack. It's just one of those tracks that lets you melt into your chair and let your mind adrift into another realm.

I probably like Pete more than his cables🤣 but he is built for customer service and is very accommodating. He has some unique wire that can work for most.

I found the NRG cables to be high quality but heavy in the bass department, and as much as a PC can contribute to the sound, they didn’t help it overall in the tone and soundstage arena.

I did order 2 shorter versions of his cables, after auditioning some 5 footers, to power my ADD PWR units since the value is so high from him. Another great guy to work with.
