    I believe it is possible. It was originally recommended to me by my father back in '93 when I was looking for a pre-amp. It seems he personally always hated the harsh and brash sounds of many of the other pre's of the era. He also bitched about his brother's Altecs. And today he says he got headache's from some of Carver's fairly recent sunfire pre's he owned briefly. "TOO TINNY". He said. His personal tastes I suspect. Some people like a brighter sound? He wanted something warmer. It always killed me when he set everything to FLAT. (The food he eats is pretty bland too. But that's another discussion.) To each his own I guess?

    I think it does, yeah. Not as "heavy" in the low end, but it'll still let you know the bass is there depending on the music program. Sounds very smooth and balanced to me.

    My 1st amp was a Rotel 45 wpc int. amp. Omega Z7000 speaker and a TT I don't remember. An Akai wedge shaped cassette deck. That deck could record. Play back sucked.

    For sale. Round Two!

    Well in light of me recent life events, this guy's for sale for anyone that's interested. Now being that some of us have WOPL's hanging around and MIGHT want to hook this doggy up to one, I would strongly suggest that if it's your intention and you let me know, I'll do a quick "mod" to this guy before sending it your way.

    The thing is that the circuit behind the cap on the way out will float quite a few volts at idle. Now obviously that is only if you haven't let it bleed down BEFORE hooking up your amp, but I'm going to be transparent here and say "don't do what I did, unsuspectin'" . What I would do is give it a little bit of a load resistor after the cap to bring the offset down a little, and yeah I'll use my 400 as the guinea pig for it but not after a quick volts check. From what I understand and with a few pointers from Joe, basically this guy has a class A output stage.. from which direct coupling is not going to happen, but as well as that the cap will allow the bias voltage to pass through without being loaded down, so.. do .. not.. hook... it .. up to a DC amp without triple checking for any residual voltage!!

    (and btw, you can skip the whole paragraph and a half up above if you just want to use it's built in amp, which I think is rated right around 60 per. Drove the CV's nicely when I tested it the other night!)

    She's a real nice sounding piece of gear. Your choice of cap loading on the phono's, plenty of tape loops, and adjusted/deoxit'd before she comes your way.

    I'll ask what I paid for, $150.00 plus shipping. PM if you're interested, then she goes to AK next lol..

    it's stereo porn in reruns
    Nothing is misguided to it's creators, only the recipients who didn't want the expectation ruined for them.

    Hey Jer, just a question... I use a Dual Mono Class A preamp and have not noticed any issue with any WOPL. Should I be concerned? It's a Perreaux SA3. I only ask as you mentioned an issue with the Direct Coupling???

    Let me clarify that a little, as the "incident" referenced happened awhile back. The outputs of the Rotel without being loaded will "initially" have around 9 volts of DC sitting there for the unsuspected, because there is no real load on the other end of the coupling caps. When an amp is connected, I believe it's no problem. However, better be real sure that the Rotel is OFF .. and if the amp has a long bleed time which both flavors of WOPL do, it's just a triple safety check to let the amp sit awhile powered off before connected the Rotel up to it. Yeah, come to think about it I may have been doing a "hot" swap which blew fuses in the WOPL at the time..

    But in any case, what I'm thinking of doing is loading the outputs of the preamp with a 100K or thereabouts resistor to ground. At least that way the DC shouldn't be as prevalent bleeding through.

    The SA3's probably not an issue, but I couldn't tell you for sure without the schematic. With the Rotel, the schematic actually shows 12 volts DC as a nominal voltage from the output transistor's emitter to the cap which WILL block it as long as there is a load on the other side i.e. the input to the amp.
