Wow I don,t know if I qualify having a pair of SC4a,s highly modified but all share my findings with you.
I find the Dunlavys to be highly accurate with a soundstage that well grow and grow with the better ass. equipment one feeds them. I have had them set up in room,s 12x32x10. Speaker,s placed 7ft aprt 3ft.side wall and 5.7ft from the front. At the time it sounded Hi-Fi. At the time I weas running Wadia 861; Pass labs x350. Ic,s were Synergistic Desinger,s ref and matching speaker cable.
The sound was very Hi-Fi. Dry ,and univolving but large deep soundstage.
I then switched to Nordost Quatra-fil and SPM speaker. Big improvement in the soundstage and seperation of people place and things but a tad bright.
I then sold the Pass and grabed a pair of Papworth Audio M200,s. (240 watt tu be monos.) Soundstage and depth of the soundstage tripled,absolutely stagering improvement. Don,t believe anyone who siad,s Dunlavys can,t be driven by tubes. They sound their best with tubes.
I then moved to a roon of 18x15x8ft. The Dunlavys to me sound there best with large seperation between the speakers,
My qurent set up is 12ft apart 38inches off the sides and 46inches off the front, My room is heavily treated with room lenses and absortion panels. Great big and deep soundstage lifelike. I found I could still not stand the bright, thin Nordost cable and tried the Stealth Ultimate Ribbon speaker cable, yes tube amps love ribbon speaker cables. And Jena labs Fugue IC. And had all cabling Cyro treated from Jena.This proceadure greatly improves all area of PRAT.
Although my room is not large the Dunlavys have never sounded there best at this time, tom. is another day.
I have heard many Dunlavys in all diff. setting and ass. equipment. All have sounded there best widely sep.
My findings at this time is given off a system driven off a 15ft. extension cord and a non-dedicated line. I was expecting a package from Jena labs today with a pair of Symphony IC. And 20amp. switch.10g.stranded romenex and a hospital grade outlet all cyro treaded and waiting for instalation. Given the improvement from cyro treatment I,m expecting big improvement in the Dunlavys.
I also think the argument between copper and silver is manufacture dependent.These are diff. questions but all have done nothong but improve the sound of my Dunlavys.
Having heard the Theil 5 some years ago It was not my cup of tea. I,m sure it was equipment and or set up, Theil has a great reputation and therefore must be given great respect in this hobby that doesent put up with High priced shit.
The answer to your question is not easy for anyone, But weather you stick with your Theil or switch to Dunlavys only you can answer.
