      The PO has already said he does not want to re-cap an older amp.

      FWIW, Audiogon site has been infected several times. Be sure you are running good protection software. I use Malewarebytes and Avast.

      Had not looked in a while, but gad what people are asking. Used electronics should go for 1/4 ( tradein) to 1/2 retail. Less if it is not respected. Half the listings are darn near mail order new prices!

            WOW. Seriously digging the low profile.

              I added a pic just for you.

            Maybe of concern, maybe not, but the "low profile" is why my Z3 amp has such bad power artifacts. Flat not enough space for enough capacitor. Not being hard on Outlaw, very good rep, nit physics is physics.

            And any amp should have enough cooling to run, say, 3/4 power for an hour or two without cooking.
            I smoked two PE DTA amps. No cooling slots, and a suspect connection to the case bottom "heat sink"

              On electrolytic caps, Forgot to mention. Look at the cap specs. You may find, depending on value, the ESR to differ by 2 or 3 times. For some values, a 63V may be half a 50V. A 25 much higher. Of course paralleling multiple will give lower too if you have the space.

                It occurred to me, the difference between an "AUDIO" DAC and one of the portable recording IO boxes may be the ability to sense the incoming bit stream. My Focusrite can be set to 24/96K, but I believe you have to set it. ( Version 3 does 24/196 and just reading about the MOTU box that is even lower noise, uses the Saber 32 Ultra DAC) THe instructions for them make no mention of this and they have no display of the rates.

                  Much reading on DACs. I did not know Windows only supports synchronous USB Profile 1. So this is why newer DACs have custom drivers, to communicate for Profile 2 asynchronous mode, So it is now clear how toslink or native Windows can cause jitter. This could explain some of the higher distortion I was measuring, but not the two big spurious spikes. Again, shame of SMSL for not talking about the driver.

                  Another hint is the new USB 3 rated cables wil have a more consistent impedance in the center twisted pair where some cheap cables are not even twisted. Tripp Lite was one good brand mentioned. Seems a $7 cable may be worth it.

                  I think I wil order a E30. I can use my upgrades to the Muse 12V supply as the raw supply for a really good 5Volt one.

                    I'm interested in what you think of the Outlaw, please report back.

                    I've been reading a lot over at ASR and they seem to have a lot of people in the all amps sound the same camp. What are y'alls thoughts on that?

                      The current Outlaw monoblocks are a newer model than what ASR reviewed and what I own. Different mfr.

                        Only people who can't hear. I can tell the difference right away between VAS loading and Miller compensation if less that excellent tweeters, and a little more careful listening I can tell on good tweeters. As a simple difference, between a Rotel 800 series and a Parasound. Then mod the Rotel and it sounded like the Parasound. Haflers, and built to my redesign, AB, I can tell but of course, doing it I would "believe" but my wife, who cares not just listens, can identify 100% every time. Class D , so far as I have heard and that is obsolete, sound different and a little harsher than a clean AB. Specs do not measure the right thing, as many an amp have outstanding .00-something numbers. Just says we are not measuring the correct thing. I found the distortion profile and level across the bandwidth varies with topology and this is what interacts with the lessor tweeters making audible distortion in the midrange. That invalidated Hafler's comparing input to output test. It has to have a real speaker attached and you have to measure ultrasonic as the root cause for IM.

                        Now for a buffer stage, my best experience is that a modern OP-Amp is as good as any exoteric discrete costing more than a car. I so far believe one can make a DAC good enough for 100 to 200 bucks. Never heard a $10.000 DAC, but irrelevant to me anyway. I can hear the difference in a headphones amp between an NE5538 and the better newer ones, but not sure I can tell between the newer ones. Some claim to. Of course, a 741 to a TLO74 to a Signetics were big steps most can hear. Most find the Signetics good enough. Your CD probably went through 100 of them in the studio.

                        It is not too hard to make a very good amplifier. Even I succeeded and I am just an old lab rat not a real engineer. Unfortunately, it is also too easy for the bean counters to instruct the engineer to reduce from best practice. Not enough outputs. Too small a transformer, no CCS on the input LTP, less than optimal choice of driver transistors and so on.

                        Truth? It is what you can hear. Now what I hear, not what some magazine writer can claim to hear ( biased by the full page ad) and not what our fellow forum members can hear. I do have to deal with what the wife can hear. Over 40 years, I know what matters.

                          Different design, or just different job-shop?
