Why would someone do this (Would you bring home a pro?)???

Why? Well, cause I could and was curious...

I use to DJ at clubs, I had my own full setup, speakers, amps, subs, turn table, mixers, etc. I often played at mid sized (500+ people) at burn fests and such outdoors so I had to have a full setup.

So fast forward like four years and my Polk 1000p's were limping along on just highs and mids. I figure its time for an upgrade and after a bit of searching I decided on LSi25s. My Onkyo receiver worked ok for the RT1000p's but had no pre-outs and is not 4-Ohm. So I start researching a pre-amp and an amp. My speakers arrived and I still have no way to power them! So, since my DJ rack was just setting there I did some searching and found several folks using the same Crown CE2000 in their home system and they loved it. Did a bit more looking around reading specs and such and decided to give it a try. This thing is a beast, 975w at 2-Ohm, 660w at 4-Ohm. 1,950w bridged at 4-Ohm!

So my music source is my PC, with a breakout box that has Spdif and Toslink line outs. So that feeds into my pioneer mixer, which is used because it's the only thing I have that accepts optical/spdif/rca inputs and bonus is it's balanced (not that it matters that much in this case). So I also have a DBX Driverack PA that has a lot of nice features for playing live but not much for home audio. Still, its a very good piece of equipment and balanced too, so I disabled almost every feature except the x-over, then set the High outputs to full range and the Low for 20Hz to 300Hz. The full range outputs feeds to the CE2000 via balanced inputs then the CE2000 outputs via Speakon with 12g wire to banana plugs, and into the LSi25's. I keep the amp on just about 1/4 of a turn up to play it safe. Power everything up and perfect silence, no hum of any type and I grab a flac file of Dire Straits - Brothers in Arms - The mans to Strong. Acoustic Guitar sounds beautiful. The highs are there but not over powering, mids are strong and blend well with the highs, the bass, WOW! These things definitely push out the bass. I learned there were quite a few things in my room that had to be weighted down and one of the closet doors has to be cracked a bit or it just rattles to much. It's not thick boomy bass, sounds very articulate and tight. I'm no hardcore audiophile and don't know the best way to describe it but it sounds killer to me and crystal clear.

I know this type of setup is something most would never do and I did it out of curiosity and lack of options at the time, the idea all looked good on paper. I am still planing to move it all to better gear as money allows but have been thrilled these past two weeks. This week I got my Technics 1200 MK2 setup and have been going through some of my fav records. Just playing vinyl after a 4 yeah hiatus was nice in itself. So yesterday I thought WTH, lets grab my JBL 18" sub, bridge my Crown CE1000 sub amp to 1,100w and plug it into the low output. At first it just did not fit, it was boomy and sounded muttled. So after a few tweaks on the x-over and it really tightened it up, at a moderate volume it really adds a kick you can feel without sounding out of place.

So next is a PC DAC, really liking the Schiit Bi-Frost. Also in the market for a decent tube-amp. I've had it suggested here and on other forums that a hybrid approach of SS for lows and tube for mids/highs is the best way to go but of course that is subjective. I've never owned a tube of anytype and plan to give them a try. I'm thinking 100wpc to 200wpc should be plenty for a decent tube amp will do the trick. Maybe a tube pre-amp for the Bifrost DAC but not decided on that yet.

Anyway, its been a fun journey and learning experience and thought I would share it here. Lord knows no other friends are family here have any appreciation for this. Pics to follow tomorrow, got some straightening up to do first. :)

    Thanks for the feedback DSkip, I have heard from others that tube-amps go a lot farther wattage wise compared to SS, I simply don't know as I have never owned tubes. The Dynaco ST-70 was suggest by several as an entry level that wouldn't break the bank to try tubing.

    I was watching one on the bay that went for $336.78:

    Yep, Pro amps can be used in all situation... Home Theater and even 2 channel.. My front L,R speakers are powered by a passive cooled QSC Model 3500 and they work great.. The rest of my speakers are powered by Emotiva amps.
    See, just like people of all races can get along, so can the pro audio world and the home audio world.

    I'm running a Yamaha PS2500 on my LSi 9's and doing a great job. I read a thread at hometheaterequipment.com about the Crown DriveCore XLS amps. The editor and one other guy I know of have both sold their consumer audio gear (Parasound). One even tried to give his away if you could come over and blind 9 out of 10 pick his Parasound vs the Crown.

    My Jolida is only 50 wpc and is more than enough. I don't know that I'd look into Schiit. Reports suggest the sound is similar to that of the Modi, and I was not impressed at all with its performance. I'm liking the Grant Fidelity TubeDac-11 I'm demoing right now. Its a bit sterile, but nowhere near the levels as the Modi was.

    Have you changed the tubes yet in the dac11? get some vintage tubes, night and day!

    Jolida is probably the most practical brand in my opinion.

    I use three carver pro amps for my surrounds, rears, and passive sub in my home theater/2 channel system the mains are a m1.5. They work well and the fan noise isn't a problem because they are in a closet nearby, but if they were in the same room I can see where it could be.

    I build my own subs and I wanted big bass w/out the price so I needed like 800 watts so I use a QSC amp it has a fan but its new and quiet ( like a computer fan )
    I wanted a home amp but anything that big was real expensive this works great and goes real good :)
