As others have stated, PL is great gear with a top notch distributor. I have owned a DiaLogue Premium integrated for more than a year now. When I upgraded to a Luxman L-590Ax, I simply could not part with the PL. It's now happily singing as my second rig.
Ayon's "Scorpio" tube imtegrated amp vs PrimaLuna Dialogue Premium tube integrated??.
I have considered trying a tube integrated amp. The Prima Luna Prologue Premium has received numerous positive testimonials regarding its sound quality and is considered a bargain at $2399. Ayon’s new "Scorpian" tube integrated is more expensive at $4200, supposedly offers excellent sound quality, but has not gathered many press reviews. .
Is anyone familiar with these products?? Are they reliable over the long haul?? and if so, can either amp effectively drive any speaker load, including Golden Ear Technology model 7 or the larger model 5. Or have any problems driving Magneplanar .7 speaker, or any of the Martin Logan speakers. Thank you

AL, Thanks for the heads up link to the other thread. I might be a numbskull in some areas of audio, but would not use a PL or any amp to drive a speaker like GET Triton 2 which has amps built in, and I assume drives the full range of the speaker, and has no provision for bi-amping. Not all the Golden Ear Technology speaker line uses a powered subwoofers. The model 7 and newer model 5 reviewed this month in Stereophile.are passive. NOTE:: Before moving forward and considering a tube amp, I am going to change the output stock tubes in the Rogue Sphinx integrated with NOS Mullards 4003CV. The reason is simply to smooth out the top end which at high volume begins to sound tinselly and less clear. I also noticed after a month of playing them, that there is drop out or lack of fullness on some familiar CD's I play. It sounds like micro cues gets lost. Choosing the larger model 5 with larger midrange drivers would produce somewhat fuller sound, but they weigh 20 lbs more each, and are taller. And I don't want to dance them around the room to find the best spot. Actually the model 7 seems well adapted to my room and placement. I have read, that the Mullards should offer somehat fuller sound without shedding detail. If it does not produce the sound I like, then I will consider the PL Prologue Premium possibly the new Ayon Scorpion currently on sale for $3150.00.....more money and more tonnage to lift at 65lbs. BTW, Tube Depot offers a full refund a 14 day window of use I will let you know. . |
Jim, to clarify, the Triton Two used by the OP in the thread I linked to has a built-in amplifier just for the purpose of powering its built-in subwoofer drivers. The rest of the speaker is powered by an external amplifier, in his case a PrimaLuna ProLogue integrated. The "motorboating" problem that resulted was eventually determined to be caused by instability of the the PL amp when presented with a very high impedance at very low frequencies (the impedance curve for that speaker is shown here). The problem was eventually resolved, at my suggestion, by putting load resistors of appropriate values on the outputs of the amp. But yes, I would feel safe in assuming that the fully passive Five and Seven models would not bring out that issue with the PL amp, given their much more normal impedances at low frequencies. Best regards, -- Al |
To those in this thread who have endorsed Prima Luna's Prologue Premier, or the Dialogue Premier. I would like to know the following: Have you encountered RF interference or picking up AM/FM broadcasting?? Will an outboard phono box to accommodate a lower priced turntable and cartridge encounter hum,. feedback. etc. because of the tube amp?? Or a phono box like the Bellari which also has a headphone outlet?? Is the Prima Luna noted for a low noise floor?? Can the Prima Luna amp that is 35 RMS to 40 RMS provide bass slam, and/or deep , tight bass?? Thank you |
