Class D can be SOTA in sound on all frequencies. Need to hear some of the best Class D to know that. Remember, those economical  Class D amps in subs and speakers do not speak to the whole market of Class D offerings.

My Lyngdorf unit is digital so I am referring to newer amp technology in general.

With so many Class D amps and price points it's not possible so say Class D is not there yet, or I tried and it is not good enough yet etc...All that can really be said is " I tried one or two and that particular amp was not as good as my...."  We... 
Changing internal cabling, anyone use Jantzen solid conductor?
Here is the part number, yes under hookup wire and sold as a single strand. Simply twist every 1.5 - 2 inches and mark one positive and negative with heat shrink on the very ends. Do not terminate, just use the bare wire. Bested my $2000 cables an... 
No bias reading, tubes lit up, no sound
I do not think it is another issue elsewhere in the amp. It is most certainly a grounding issue. Your rewire has upset the original grounding scheme. Go back and match what was done originally. Exactly.

Crossover capacitor voltage ratings....
Your speakers even if they are rather inefficient and you play your music very loud would be driven with 10-15 volts max. Most of the time only 1.5 - 4 volts. You are fine with 100 vdc! I would not use electrolytics. If you want the best sound out...

I did not like the Devialet that much and sold after 1 month of ownership. It was ok, but nothing special. I would not use it as an example of the best this technology has to offer. My Lyngdorf 2170 is much better and only $4000 or so. It comes wi...

Good question John. It has hurt and will continue to hurt vinyl. The latest hipster fad for turntables is a fad and will fade away. Steaming, Tidal, Roon, one box digital solutions etc... are absolutely eating away from vinyl, cds and the like. No...
