EFFICIENCY

oops that should be ohms.............my difficieny

Both speakers are 4ohm Thiels,I believe they go down to 2.3 ohm.

Both are Thiel speakers,the SC6 is,I believe rated at 86db and the new 3.7 at 90db.I have heard the 3.7s through three different amps,Krell and two different Classe,one of which was mine.The SC6 I heard through an Arcam 85 amp, in a barren unfinished basement.Of course the 3.7s did sound better in the perfect listening rooms,with more power,however the 3.7s cost more than double the amount of the SC6 and the SC6 is in mint condition.

Yes,Pubul57, there is truth in some watts sound better than other watts.No,Jmcgrogan2, I am not thinking out loud,there are many here that have already experienced what I am about to experience and some that can give good sound advice to help me in my decisions.
