luvdunhill Posted October 15, 2016 Author Report Posted October 15, 2016 Well, as you can tell color matching is hard - as is photographing color differences. Trying to choose between the four swatches here for some grills and having a hard time because the wood looks different in various lighting..I am leaning towards the far left (towards the window). None really match anyways, so could do black.Oh also, a bunch of these. Pretty amateur but they should look nice enough. I have a mounting scheme I am hatching. 2
UFN Posted October 16, 2016 Report Posted October 16, 2016 FWIW I'd vote for the black one as well //UFN
Pars Posted October 16, 2016 Report Posted October 16, 2016 Black as well, and showed these to my wife, who also agreed with this.
Dusty Chalk Posted October 16, 2016 Report Posted October 16, 2016 tweed No, seriously, you all are putting way too much thought into this, they'd all look fine in a large enough swath. I'd base it on what it does to the sound. Are they all the same thickness/weight/density-of-weave/etc.? I'd use the thinnest, most inert, least "muffling" material. Synthetic over organic materials. I was actually going to regrill my old pioneers with lace at one point.

Looking for 5.08mm pitch alternatives to the Molex SPOX that I use some.
Laowei Posted October 16, 2016 Report Posted October 16, 2016 Exceptionally beautiful modern TP-1s. Did you go whole hog with PM-4A Lowthers in them? Back in the day, I used PM-7As, PM-2Cs and PM-5As in front loaded Chapman horns. I don't think you can't get enough alnico flux in those drivers to make them even MOAR BETTER. Also, light bulb diffusers help to minimise HF beaming. Geez, I'd love to hear your setup.

I rather like them:http://www.te.com/usa-en/plp/mate-n-lok/ZndJ.html Exceptionally beautiful modern TP-1s. Did you go whole hog with PM-4A Lowthers in them?I am using DX4s. I could resize the compression chamber with some blocks and retro fit the PM-4As easily enough though. Do they come up reasonably on the used market?
Laowei Posted October 16, 2016 Report Posted October 16, 2016 (edited) Never seen Lowther PM-4As on the used market, going back 20+ years. The magnets are huge beasts, needing a rear bracket to take the weight load off of the front flange. Got my Lowthers when Tony Glynn first established Lowther America. Heard most of the old and new variants in my horns at that time. My preferences were always for the alnico motors. YMMV. Edited October 16, 2016 by Laowei
luvdunhill Posted October 16, 2016 Author Report Posted October 16, 2016 Put up some backing strips for the new CD shelves. Working on getting the actual shelves mounted. 2
luvdunhill Posted October 16, 2016 Author Report Posted October 16, 2016 Oh, I blame Aardvark Baguette. That needs to be said 8
johnwmclean Posted October 17, 2016 Report Posted October 17, 2016 Well that filled up quickly... Looking very nice.
wink Posted October 17, 2016 Report Posted October 17, 2016 Nice collection. Is that the main collection, or just the most referenced CDs..?
luvdunhill Posted October 18, 2016 Author Report Posted October 18, 2016 Project number two will reveal that. 2

Dusty Chalk Posted October 18, 2016 Report Posted October 18, 2016 I know how both you and they feel.

I replaced a Rega Brio integrated with the salas phono stage, BA3 pre and F4 power amps. Overall the improvement was very impressive. Much better control of the low end and also a wider soundstage with more "air". Overall the sound is quite "musical, but not the most detailed.( the ba3 is not know for being the most detailed amplifier out there.). When I connect a digital source there is also some improvement so I can say the the phono stage is responsible for some of that nice sound! Here are the latest pics: Dirty psu section with line filter. Dual mono PSU umbilical. The black knob works as on/off switch, input selection and volume control. When turned on there are 2 numeric led displays on behind the black acrylic for volume display. 64 steps Control board for the attenuator/source selector. Remote control receiver on the front side, Cat5 wiring for signal. Salas SSLV regulators, BA3 front end at 30V and relaixed passive attenuator. using vishay self resistors. The control board for the attenuator is in the front panel and the power relay/5V control voltage section pcb is in the psu case. 8 wire umbilical carries control wiring and dual mono DC for the regulators. "gain" is the output from the BA3 preamp, "0db" does not have any active circuitry in the signal, so it is a passive preamp output, "loop" simply outputs the selected source, so it is just a source selector. The two AC female connectors are controlled by the preamp on/off relay switch (10A/250V), so when I turn the preamp on I can turn 2 other devices at the same time. ATM using one of them for the phono stage, might feed a DAC in the future with the other one. Preamp PSU. System in my DIY oak rack (solid oak kitchen countertop cut to size) A small video of the system playing, you can see the F4 power amplifier behind the left speaker. It will eventually be placed in the large lower opening in the rack, but I need to build ventilator to extract all the heat (200W) from those heatsinks. Some sort of undershelf with 140mm computer fans is on the way. https://youtu.be/OpMUCAIiMUY Edited October 18, 2016 by MASantos 6
Kerry Posted October 19, 2016 Report Posted October 19, 2016 That's a nice collection you have there. Nice job!
mwl168 Posted October 19, 2016 Report Posted October 19, 2016 Very very nice builds. Congrats! Do those L shaped brackets come with the chassis or something you added on your own?

Do those L shaped brackets come with the chassis or something you added on your own? The ones supporting the front panel? They are an extra from hifi2000 to make the front panel without visible mounting holes.
Pars Posted October 19, 2016 Report Posted October 19, 2016 Very nice builds as well! What are the RCA connectors used on the preamp? Sent from my iPhone using Tapatalk
