The Above , is not totally true . Carver designed his amps to Null other amps . Most bigger Carver amps 200x2 and above , came with alittle chip attached to it . If i recall correctly the older 1.0t was made to sound like the Conrad Johnson Tube amp .
If you take the Carver 1.5t and compare to the Carver 1.0t , the 2 amps will sound different , two totally different sounding amps

.
The TFM series ( without the X ) , i think where designed to sound like his own Silver Seven Tube mono blocks .
