    I am definitely not going down that road. Spent the past 40 years or so screwing with things for a living. These days I buy what does the job I need it to w/o upgrades high maintenance and troubles. Tube amps are not for me. Not sure I'd wanna deal with class A heat. 

     

    Than

    I have had my QuickSilver tube amp for 23 years

    Still on original tubes No repairs ever. ,🙄

    I DJed a couple dances over the past few years doing that.  I have Amazon Music Unlimited and I downloaded each song I was going to play in the highest format that was available.  I connected a 1/8” to stereo RCA cable to my receiver.  Worked great and sounded fantastic.

     

    I listened at home first and was really impressed.  I have no idea what DAC my laptop has.  It can’t be that high end since it’s only a $300 HP laptop.

     

    You shouldn’t need a pre-amp if you were connecting it directly to a power amp.

    I gave a fantastic QuuckSilver pre sitting unused

    My Holiday CD goes right to the Crown K2

    Jubilee Amplifiers?

    I wonder if you can use a pair of big amps with the Heritage Jubilee? I was thinking 350 W per channel for the HF/MF and 500 watts per channel for the low end.

    40 Watts more than sufficient for Mid/ High

    at this moment i drive my LF cabinets with a Hypex 500wpc class D amp, just did a comparrison with one of my Crown K2 amps but for now my impression was that the hypex has better low end and more punch.

     

    for the 402`s i am switching between the First watt J2 and tubes. not sure what i like best yet.

    both the J2 and the LM219IA are 25 watt amps.

    i am a tube guy but you need a really really good tube amp to keep up with the J2.

     

    will try my Mc275 on the horns next week, and after that a Sun Audio 2A3 from a friend of mine.

    something in me doesnt want to part with tubes :P but the J2 is no nonsense and top sounding.

    Really ??

    Class  D ...more better??

    Shocking. 🙃

    Question about speakercables

    I do think 2.1mm (12 American Wire Gauge) wire will be enough. 

     

    What amps and preamp are you using?  Some people once thought long, especially balanced (3 wire microphone cables) and short speaker wires were the ultimate.  Can you put your power amps on or behind your La Scala's and run long cables to them? 

     

    I use 3 pair twisted, then braided CAT 5e cables for speaker wire.  They amount to about 2.3mm (10.5 AWG) wire.  The insulation and all that braiding results in a low resistance, capacitance and inductance speaker cable.  They are about 5 meters long.  I could not hear a difference between old 12 AWG Monster cable and my homemade wires.  But they look good!

    I also failed a double-blind test at Klipsch HQ in Indy with similar cables many years ago.  Klipsch said their braided CAT 5 was -3 dB at 300 kHz! 

     

    My bottom line is that when the resistance is low enough and inductance and capacitance are not significant, you have a good speaker cable.  Buy a large diameter stranded wire and don't worry. 

     

    I can not hear 300kHz. ,. ,🙄

    I am old, must be my hearing

    Ixam happy with 12000 HZ
