Direct Drive vs. Idler Drive vs. Belt drive
For idle drive you need a very accurate mechanical production and professional design.For DD you need high tech engine and electronic control system.For belt drive you can get a cheap toy car engine, build it in your garage and sell it for thousan...

Al EMT DD are good suspended.Two my friends -One sold Linn LP12 for EMT 948 and other one sold Sota for EMT 950.Other my friend prefer EMT 948 over Kenwood L07d and Technics SP10mk2, but he likes Yamaha GT-2000 as much as EMT. I think than EMT 950...

I payed $3300 USD!!! for Nottingham with Spacearm included taxes.The price was higher because I was living in Israel that time. I don’t care about brand new price of EMT948 in 1980.Personally, I didn’t pay more for EMT than I payed for Nottingham...

Hi @terry9 ,Nottingham Analogue  Sapcedeck is not entry level. It was a third level after HORIZON and INTERSPACE. I bought Nottingham Sapcedeck with Spaecarm in 2002 a brand new by full price.I bought EMT948 in 2011 on eBay used by 2400 Euro. Yes...

Hi @akwilson501 ,What kind of capacitor do you use?The capacitor quality and jumper wire quality is very import too.I prefer paper in oil capacitors for smother sound.Regards,Alex.

After Lenco I use EMT 948.It is a number of levels over Lenco and Nottingham Spacedeck.Other my friend audiophile and musicant (flute player solist and conservatorio teacher) threw away his heavy platter Sota turntable after buying EMT 950 DD turn...

I had Nottingham Spacedeck and moved to heavy plinth Lenco 78 with SME 3009mk2 tonearm.Lenco won in term of PRaT, piano and organ tone, better bass, better instrument separation, more musical. No rumble.And Lenco wasn’t expensive High End turntabl...

Super tweeter for FullRange Driver
In my specific case it is 15 degree. I measured it.You want supertweeter will add more high frequencies over 10KHz. If the angle is more than 30 degree it seems to be not good.

Super tweeter for FullRange Driver
In my case adding T90a tweeters didn't change tonal balance too muchbut made sound much more refined.Not just added air, soundstage and high frequency extension (as was expected), but also made better separation, more realistic tone of instruments... 
Super tweeter for FullRange Driver
My speakers Altec 604E. These speakers have high frequency extension just up to 12KHz.I did experiments with back of ceiling firing tweeters. I used Morel MDT30 tweeters with 1st order filter. The effect of  back of ceiling firing was like a sali... 
Super tweeter for FullRange Driver
