ok..so here I am at the end of September and I cannot even know where to begin on the different gear and tubes I messed with.What's my set up now..Still the C220 only with EH cryo treated tubes, Manley Chinook with EH tubes as well, Harbeth Compac7 ES 3's, and yes, an MC 152 is in my rack going toe to toe with the Parasound A21.So far the Mac is very smooth and detailed, nice, the Parasound, detailed, powerful at low levels, punchy bass, especially with the EH cryo tubes.The Harbeths are 6 ohms vs the 4 ohms of the Mini T's. Both are power hungry speakers.The Mini' t's are gone, sold shortly after the arrival of the Harbeth's. Will the Parasound be dealt the same fate? I'm not noticing any sonic differences using the 8 ohm output when compared to the 4 ohm output but decided to just leave now on the 8's as the tests results on this thread show more power through the 8 ohm terminals.There is definitely a difference in sound provided by these two amps. right now, being used to what I hear from the Parasound, it has the edge over the Mac.It has that extra oomph that makes the harbeths jump out at you. Of course I have been tweaking this amp for 2 years, and with the harbeths for 3 months. The Mac has been in house for 3 days. I did get it from THEMUSICROOMAUDIO.com so I have 30 days to return it should I go that way. It was lightly used and they gave me a great deal on a used LFD LE MK IV I snatched up locally as a trade in towards the Mac. They are also very interested in my A21 should I want to sell that to them. So just when I thought I had some free time, here I go again swapping inputs and outputs and cabling and playing lps, cds over and over..lol. The Mac is beautifully built and quite heavy at 75lbs.The packaging is overkill which assures it's safe delivery. That in itself is a job to unpack it. I will be updating periodically.
