My complete system uses T.G. Audio power cords (except my transport), per recommendations from the "Bound for Sound" audio newsletter (I'm only a subsciber to BFS). There are three types of power cords that Bob makes:
1.) HSR "i" Rev II: for use with SS equipment, transports, DACs,SS preamps, smaller amps..etc.( I use the "i" on my DAC).
2.) HSR "A" Rev II: For tube-based products, but can be used on SS products as well with great results. ( I use the "A" on my Herron preamp).
3.) HSR "i2" ( i-squared) Rev II: For use with high current amps..etc. ( I use the "i2" on my two SS amps configured as mono-blocks).
All of the PCs are excellent and a good value for the money. These PCs have networks in them that is voiced by Bob Crump. Although I am a tweaker and regularly get the upgrade "fever", I have not changed the PCs listed above. NOTE: I use a Mapleshade "passive" Planar PC on my transport, which I upgraded from a Harm Tech 11.
You can purchase the T.G. Audio PCs from the two sites listed below. ( I'm sure there are others as well).
Hope this helps...ENJOY!
