anyone bi amp a pair of ess amt1d active xo ?
The slope may be to steep. I'm not familiar with the Rane other than i have seen a picture. I would say your ESS would have a slope at 12db/octave and the slope would finish around 800hz not begin at 800hzThe woofer would also phase out completely...

What slope are you using? What are the passive crossover specs for that model?

Originals vs. reissues/current issues
Not sure about that one. They had a progressive fusion thing going on. Works-1 and Tarkus were some of their best work. Works-2 had a few decent tracks but was really no comparison to Works-1. The rest of their albums were hit or miss and the last...

Amp for JBL 250 Ti
Autoforms in Mcintosh amplifiers give the end user the option to match low impedance curve speakers to the amplifier autoformer transformer and be able to operate the amplifier safely. As far as sound quality with Autoformers thats a whole other d... 
Amp for JBL 250 Ti
I didn't think autoformers were used until the Mc2500 or 2600 in the bigger industrial look amps and I'm not sure about any of the blue meter Mc amps As far as the matching Ohm outputs that would be the different locations where the power transfo... 
Amp for JBL 250 Ti
Autoformer is going to be more circuitry to the amplifiers design and signal path. The 250Ti should not have any wild impedance curves not sure if they are 8 or 4 ohm load. Some reason 6 ohms comes to mind. In any event they do need power so your ... 
Amp for JBL 250 Ti
I responded to your post on AK for a Mac amp. For other potential amplifiers you may want to consider an with a higher current high headroom amp like a Mark Levinson 23.5 or a Jeff Rowland model 5. Super high current and I think better bass contro... 
Best REEL TO REEL blank tape?
Well first I will tell you that recording your vinyl to open reel is going to become an expensive undertaking. Unless you have some very prized collectable albums your money would be better off spent on a higher end Analog to Digital converter lik... 
Tannoy Gold Monitor 15"?
Tannoy has always had a cult following for their big horn speakers. The GRF autographs with the golds are the mac daddy's. The only thing about the Tannoys I cant seem to get past is the "honk" in the midgange when you push them.Take a few strong ... 
Another biamp thread.
If you're going to remove the passive crossovers I would do some research on the speakers you may be interested in and see how complicated the passive crossover network is designed. The more complicated the crossover design harder it will be to in... 
Velodyne ULD 18 questions / help
You are correct about Velodyne tweaking each amp and driver as a set. I do know the main difference between series 1 & 2 are that the series 1 has the DIN style cable from the amp to the sub. The series 2 uses an RCA style connection.The tweak... 
Velodyne ULD 18 questions / help
I was under the impression the series 1 amps are the same for the series 1 ULD 15 or 18 and same for series 2 Series 1 have the DIN cable between the amp and sub Series 2 have an RCA connection from the amp to the subThis third wire is how the amp... 
Dueland Alexander Copper Foil PIO Capacitor
Expensive but very smooth & detailed sound. I used them for a speaker passive crossover rebuild. Not sure about using them in an amplifier. They are quite large compared to the conventional round capacitor.
