I have owned BD-Design horns for over ten years now, starting with the Oris200 with AER MD2 and for a few years a pair of Orphean horns MKII. I have gone through many bass solutions over the years, including the BD15 compact bass system. After trying many different tube amps (Pentodes and Triodes) with the Orphean horns I just couldnt get the sound out of them that i thought they should produce. I was disappointed and went looking for another speaker solution, finally settling on a pair of Gradient Revolutions. Needless to say a completely different speaker solution from the Orpheans horns. I was tri-amping them with Nelson Pass First Watt amplifiers and also built two further bass towers giving me a total of six 12" open baffle woofers. I enjoyed them for nearly a year, but the Orphean horns were still calling me from the garage, asking for one more chance. I connected the Orpheans to my First Watt F3 (10W SS, class A) using a Marchand active crossover at 250Hz 24dB/octave to pass low frequencies to the open baffle bass towers. To put it simply, I am stunned at the sound and have fallen in love with the Orpheans all over again. Using the FW F3 amplifier I have finally heard what the Orpheans are capable of, and I am thrilled. It has been a long journey, but I am home at last.

Welcome back! What is best stays best!:hi:

It’s all about how things coincide together …

How are you happy with bass now?

:bass:

Cheers,
Gasper.

I am very happy with the bass, I find the dipole base to be very fast and integrates well with the Orpheans. I found the compact to be giving too much energy around the crossover point, which made the Orpheans sound closed and muffled. It is a whole different sound now with faster bass.

Nice to hear that! :)

I do not want steal the thread, but I want share my experience with Orphean.

To my personal opinion Orpheans need some effort to get them work. Remember guys this is only my view on this.

At this point I can safely say that Orpheans with Ref2010 bass enclosures (Built by my self) is the best system I've owned do far. I've had Cain%Cain Abbys, Oris200, Avantgrade Duo and now Orpheans. The dynamics, big live like feel, speed are virtues I appreciate. Now for the first time a am excited to listen classical music. This never happened before with my previous systems.

Today I play music mainly via laptop, using foobar2000. I have Triode TRV-M88SE Monoblocks without preamp.

I said Orpheans demanded some effort and I'm gonna tell what it meant in my case. Firstly I needed to get rid of the hard HF. I needed resistor in series with the tweeter - in fact i have few of them in a closed box. I can now step by step to reduce the energy if needed just by turning the switch.

Now second problem was the bass. I got it better just by getting rid of my 300B Mastersound amp and have kt88 amp instead - too much round bass in that 300b Italy made amp.

I never got the bass integration with Orphean to work with Bert settings in the hypex amps. He tried to help me the best he could. Still the sound was like listening to two different systems - a lot of lower and mid bass and thin middle frequencies (or upper bass). :unhappy:

Then I did something that Bert told me not to do! I trusted my ears. In my case the sound just got so much better when crossed the bass in 350 hz - 400 hz - I have now four different settings to play with. The sound is fuller and more live like. :yes:

I do not know is it my room, listening distance (about 2, 7 m) or what that makes the íntegration bad with the original settings. If some has an idea why Bert's original crossover settings in hypex did not work with me I would gladly hear it.

Anyway I wanted to share my experience. If you have orpheans, do not give up with them. They can give you a hell of a ride :) :grin:

Samoore, I heartily confirm everything you said about the First Watt F3s. I have a DIY triamplified horn system, folded bass corner horns, Oris 150s with AER MD3s and Fostex t900a
bullet tweeters. For about eight or nine years I used Cary audio 2a3 SET monoblocks to power the Oris and Fostex. After listening to an F3 on the Oris horns I sold the Cary 2a3 monoblocks and bought two First Watt F3 stereo amps hand built by Nelson Pass himself. The change these amplifiers made in the sound of my system was wonderful. They do absolutely everything right. I have owned and used many different tube electronics ever since 1972, but now my stereo is tube free and sounds better than ever. To anyone who still thinks solid state amplifiers can not equal the richness, immediacy, dense textures and soundstage of good SETs I recommend they give the First Watt F3 JFET amplifiers a listen. They might change their minds.
