planet10 Posted February 1, 2021 Share Posted February 1, 2021 Thosephase plugs have a weak EnABL pattern. It will have next to no effect without the rest of the driver done. EnABL2 has placed the ringsets in more useful locations. [img] Link to comment Share on other sites More sharing options...

Indeed there are those who do not have the hearing acuity to discern the differences or who listen to other things than what EnABL brings will get no benefit. But ther eis a difference and you can discern it EnABL can bring a whole new level of information from your hifi. It takes me less than 30 sec in a double blind test (with approprite recordings) in a doule blind to pick out teh EnABLed drivers. The 1st time it took an afternoon for me to tease out the differences but once you know what is now there it seems stark. dave Link to comment Share on other sites More sharing options...

planet10 Posted February 1, 2021 Share Posted February 1, 2021 Just the kind of response expected. Without an open mind you likely could not “hear” the difference even if you could. You of course are free to ignore it, others can make their own evaluations, and if you haven’t heard it, you have no basis for complaint. dave 1 Link to comment Share on other sites More sharing options...

I'll let people know they have to "imagine" there is a difference because there is no measured proof. Imagine I had millions of Dollars in my bank account !! Damn. !!

We can’t detect “a little better” or subtle changes. Gross changes maybe. Link to comment Share on other sites More sharing options...
muon* Posted February 2, 2021 Share Posted February 2, 2021 The issue is people use themselves and their own individual experience to measure what others can and can not perceive. Using a data set comprised of 1 subject. Link to comment Share on other sites More sharing options...
xlr8or Posted February 2, 2021 Share Posted February 2, 2021 (edited) Back to the topic. I'm building a new Melwood No. 3263 man cave out the back to house all me valves. This is a very important 'audio build' for me as 168m2 of internal floor space in the main house has already been filled up with glass bottles, valve amps and valve testers amongst the other trivial audio staff you find in listening rooms around the house. Edit: I need recommendations on vintage storage solutions for archiving my tube collection to take me back to the mid 20th century. An example of what I am looking for is below. Ashtray recommendations for pipe and tobacco smoking are also welcomed. Edited February 2, 2021 by xlr8or 4 1 Link to comment Share on other sites More sharing options...

mwhouston Posted February 4, 2021 Share Posted February 4, 2021 Built a tube Radi0kit MM phono preamp a few months back and also used their kit PS. Both very, very good. Had a temp setup and listening to vinyl on phones using the new tube phono stage. Good for a couple of days then I did a slight rearrangement with the phono stage and from then on it has a huge hum. Spent a little time at this point trying to workout what went wrong. Then spent all of yesterday morning again trying to find what happen. I had a second PS board complete and swapped it over. No improvement. Anyway it proved the PS good. Pulled the phono stage apart, checking components etc and solder joints. All good. I decided to make a whole new phono stage as I had another un-assembled kit. But laying awake last night I thought today I will try some different earthing setups. Sure enough connecting the negative of the HT to the Al chassis and mains earth to that (the PS enclosure is at mains earth) the hum vanished. What I think happened was at the initial construction the negative of the PS was touching the chassis (by accident) as I was using insulated RCAs this - initially- wasn’t meant to happen. When I moved the preamp a few days later that accidental connection was broken. Long story short the phono stage is back in service and sounds excellent. No hum and nice and detailed. Good looking too. 2 Link to comment Share on other sites More sharing options...
mwhouston Posted February 4, 2021 Share Posted February 4, 2021 I had a chassis with a fully assembled PS in it but no amp board. I happen to have a Tripath 180W T4 (latest release) on hand and brought the two together. Initially I want an attenuator with the amp so a preamp was not required but I could not get this setup quiet enough. Now it is a power amp (100W based on PS limits) and sounding really very nice. I noticed on a few tracks, while playing it loud, bass drum in an orchestra was extremely percussive. You could feel the air in the room compressing. Chest slapping. I wondered how low the amp would play. Using warble tones the amp is dead flat to 30hZ (where the front door rattles) near the limit of my 12” speakers (Fs=25hZ). Some output at 25hZ then nothing at 20. Box is 60ltr sealed. This beats my 500W Holton which’s is down 3db at 30HZ. Not bad for a very inexpensive detailed and warm sounding amp.
