    Does anyone know where I can get DMA200 transistors?

    Matched with what? The VP mosfets specified should match with the rest of the system since they were used in the original amp, no?

    Does anyone know where I can get DMA200 transistors?

    Most likely due to heat. They are putting on bigger heatsinks.

    Does anyone know where I can get DMA200 transistors?

    Stephen Sank diagnosed the problem with my friend's Spectral DMA-200. There are several DMOS FET that are bad or about to go bad. I need 4 DMOS FET model VN0116N5 or VN0120N5. and then also need to replace 4 DMOS FET PN0116N5 or PN0120N5 that are probably near failure. Total 8 pieces. Does...

    Spectral DMA 300 RS/SV

    I am considering DMA-250 that has been sold and bought several times; so I don't know its condition. It is supposed to be universal. Do you know roughly how much Spectral charges to refurbish it?

    I am thinking about an old DMA-250. Does anyone know roughly how much Spectral will charge to refurbish it? Is it worth refurbishing it?

    Spectral DMA 300 RS/SV

    My friend wants to replace his 30 yr old DMA-200. Is it really true that in order to buy a new Spectral amp you have to buy a new Spectral preamp too? Or was that just for DMA-500?

    Deciding between 260, 360 s2, 250 or 360 s1...help a brother out!

    I have a friend whose DMA-200 is dying. He is thinking about buying a new Spectral amp. I read somewhere that if you want to buy a new amp you also have to buy a preamp to go with it. Is this true? I have trouble believing this.

    Deciding between 260, 360 s2, 250 or 360 s1...help a brother out!

    It is supposed to be 250W on idle. I am guessing about 10W in class A.

    I got the answer on this. Spectral will not service anything this old.

    Deciding between 260, 360 s2, 250 or 360 s1...help a brother out!

    My system is not SOTA. Preamp is Dan Sachs tube preamp, Lumin X1 streamer/DAC and Sound Lab ESL speakers. Currently using X350.5 but it generates 600W of heat just on idle in my tiny room: 11 x 9 ft. I was looking at a used Spectral since they generate only 250W and low class A bias. I like the...

    Deciding between 260, 360 s2, 250 or 360 s1...help a brother out!

    I am not so concerned with power as much as SQ. Some comments indicate that the SQ of 360 s2 or 300RS is noticeably better than 260. Do you agree with this?

    Spectral DMA-200 advice

    When you say When you say "Yes", did you mean you had it refurbished? Do you think SP 3 is better than the current ARC Pres?

    Spectral DMA-200 advice

    SP-3? They are ancient. Have you compared them to Spectral preamps for your DMAs? Did you get them refurbished?

    Deciding between 260, 360 s2, 250 or 360 s1...help a brother out!

    I am considering either DMA 260 or 360 S2. Other than power, do you think there is much difference in sound quality? Can they play nice with a non-Spectral preamp?

    ... an odyssey with spectral dmc10

    My friend has DMC 20 and DMA 200 and it has a beautiful clear sound. How would you compare that system to DMA 100 and DMC10? Other than the power difference, of course.

    So, even without the megahertz preamps, are you still seeing the high resolution in the DMAs?

    Spectral DMA-200 advice

    My friend has the old DMA-200, running with DMC 20 and Quad 2912 speakers, and they sound exquisite. He never had DMA-200 recapped. Since it must be about 30 years old, isn't it a time to recap the electrolytic caps? How much does Spectral charge for recapping and other "refurbishment?" Also he...

    Do you have any experience with a Bardo? I love to hear more about it. I read one review and it wasn't too great, esp for bass. Where do you service them in the US?

    Lumin X1: Enabling an Even Simpler Yet Better Sounding System

    Roon is an interesting idea. I prefer the Roon interface over Lumin. I guess it is time to consider purchasing a Nucleus. Doesn't going through the equalization program decrease resolution?

    Lumin X1: Enabling an Even Simpler Yet Better Sounding System

    When I use Lumin X1 to hear Diana Krall, I get a fair amount of sibilance. The same album on vinyl has much less. Peter at Lumin suggested that I use the Low Analog Output option. Tried it, but it only seems to have decreased the volume and resolution. Any suggestions?

    Lumin X1: Enabling an Even Simpler Yet Better Sounding System

    If you are using Roon Nucleus+, are you not using X1 streamer function? Nucleus is a streamer too, correct? I have been trying to like the volume control on Leedh, but I like to skip around different albums and different tracks, which means I have to constantly adjust the volume level via Leedh...
