  1. Hate to interrupt the geopolitical discussion, but I left my BHSE on all night yesterday by accident (read, "was pissed") and it didn't burn the house down. Thanks Kevin and Justin.

  2. I think you're mistaken. It definitely did.

  3. The other day I had lunch with Craig and Stretch. Pity them. But not because of the food, because that was fantastic. Plus wine. We were with Stretch after all. Tonight was another fantastic dining experience. No wine because of scotch. Good bye UK!

  4. Indeed, PM me for the delivery address... In other news, never buy a 4070 that has had the earpads replaced... Do it wrong and they sound incredibly bad, next to no bass and just treble. Now I have to buy some new pads and try to get them retuned. I did get a nice package yesterday, the aforementioned 4070, Lambda Pro, Lambda Signature, Nova Signature, 404 (in rough shape though so full resto on them), SR-SC1, 404LE and a mint Alpha Pro which will not be killed.

  5. Have you ever tried to export to China? I have. They refuse to accept CE and UL approval, and insist on putting a product through their own process (protocol 60) - the company is 9 months in and counting, driven by a Chinese speaking employee. Oh - and you have to supply full engineering drawings, full BOM and documentation pack translated into Chinese, and a product for "testing" - no ifs and buts. The process takes an eternity, and you have to down your pants and ask them to kick you right in the ass in order to sell into China. So do I believe that there is a policy of obstruction to exporting to China? Yes, absolutely. Where does that policy originate? The Chinese government in whatever shape you want define it. That is leaving aside that they have had a product and manufacturing data for 9 months......

  6. So here's a progress update on my T2 mini build. I started off with the a golden reference version of the T2 supply. Had a couple of issues. There was some 60Hz noise I was hearing (I'm guessing from the integration of the negative rail supplies), which I can probably solve for. Also, the current limiting, which works, wasn't fast enough when there was a shorting issue with the amp on the negative rail (FETs in the output section shorted to the heat sinks). It would pretty much blow out several components in the supply. I decided to go back to the original design, but as a shrunken version (206mm x 200mm). I did some small mods (added cascaded current source for the 30V supply to the opamp and added some additional spots for compensation caps. I finished this over the weekend and have spent some time listening. I've still got to tweak the PS (some small oscillations - probably because I was experimenting with the .1uF cap to the negative input of the op amp and added a .1uF cap across the voltage divider). My BK multi-meter is showing between 1mV and 0 on the AC setting. I've had some of the supplies on the scope but will need to go through all of them. This causes some very faint background noise. The amp has had it's fair share of issues, primarily with the output FETs shorting to the heat sink. I've had this once on the left channel and three times on the right. I believe it was that some thermal compound found it's way inside the collar of the thermal washers (7721-3PPS). I've cleaned these up and have had the amp on for 12 hours now with no issues. Also, the right channel DC test points are all pretty much spot on, but the left channel has an issue with the -543V test point. It is sitting at -502V (the rest of the DC test points are pretty close except for the top of the batteries that sit at +238V). I've been looking at this issue for a while, but haven't figured it out yet. I've got to focus here a bit. Any thoughts would be appreciated. I also have to finesse the battery adjustments to get rid of some occasional noise coming through the right channel as well. I have had my 404's and then later O2's on this beast. Wow, how nice It's been too long...

  8. The 4070 has ports running down the sides of the baffle on each side. Plug those and the bass has nowhere to go hence massive cancellation issues.

  12. Dude was only 57, also ageless. Who'd have thought to have a pre written obituary for a guy who has been the same age since 1992? Man this sucks.

  15. I had a pair of 57's on stands - and my wife knocked one over. It was saved from damage by the speaker cable, but the super expensive silver connectors got trashed. But those 63's were responsible for my obsession with high end audio - visited a room at the Heathrow show in the early days of Meridian when they were importers of Mark Levinson. Meridian CD player into dual mono ML pre, class A power into a pair of 63's on stands. Brothers in Arms was playing - and it sounded so completely different to what I was used to hearing. I left that room determined to aspire to that sort of sound quality. Little did I know where that go....

  20. Their stance on DSD is well known so I wouldn't hold my breath. I must say I agree with them as DSD is just another way to sell people shit they already own

  21. ^ that. I'm glad someone spoke up. Too tired to respond to trolls and ignorant posts these days so I just stay silent, but someone at some point needs to set the facts straight.

  24. George's suggestion to up the current limit worked like a charm, everything's up and operational. Sounds good, a bit of popping/clicking but nothing too noticeable. How should I go about tracking that down? For my personal use I don't know if I care enough yet, but I might try to fix it when I redo the internal wiring/etc. Knob courtesy of insanity, I probably should have measured it before sticking it on
