My Final Amplifier Purchase - What Would You Buy?


I'm a lifelong audiophile/music lover and earlier this week, I had a life changing event. As a result, I am now in the position of purchasing what is almost certainly my last power amplifier.

To quickly explain, I was just notified that my entire department will be outsourced, effective September, following the completion of a transition. The buyout is not great, but they do extend my service time for an additional period, allowing me to begin receiving my full pension in September. So essentially I'll be okay financially, but certainly not enough to buy this level of audio gear down the road.

So, what this leads up to is that I was in the market to buy a quality used power amplifier (up to $4000.00 budget)to upgrade my system. I can still manage to do that, but clearly need to do it soon while the paychecks are still coming in. In the future, I simply won't have the financial means for a purchase like this.

Thankfully, the rest of my system is solid, and this should essentially complete things for the future. I'm very happy with the preamp, but I suppose that could "possibly" change one day, maybe to tubes,in a break even trade, but beyond that,if it even happens, the system should remain what it is.

Current system:

Meridian G02 Preamp
Meridian G08 cd player
Olive D4 Music Server
Silveline 17.5 speakers
Marantz SA8004 SACD player
Bryston BDA-1 DAC

and the power amplifier that I will be replacing:

Atma-Sphere S30 MK III.1

I truly love the S30, but a friend recently upset my satisfied audio world when he brought over his new Plinius SA-103 amp and that changed everything. Even more than the sound of that amplifier, which was superb, it became readily apparent that the Silverline 17.5's really only open up and fly when given that kind of power (100 wpc or more.) I also tested it further with a second amplifier and verified that the power is key to really getting the most out of the speakers.

I have long been an avowed tube lover, but there simply are not many options with the kind of power I am in need of, that fall within my budget. I've included a few as options below that put out 75wpc, because in my experience, thats roughly the equivalent of 100 wpc in solid state.

In a perfect world, I would just move up to the Atma-Sphere MA Series, but my budget is far insufficient. Also, a key factor is that I have a small room, even the M60's which (might) have enough power, would create a literally sweltering environment. Trust me on this, I've even talked to Ralph Karsten about it previously, and he agreed.

Based on that, some earlier suggestions here in the forum, and a massive amount of research, I have narrowed things down to a number of choices, which are, from my perspective, likely the best options. What I am truly in need of are any thoughts, expertise and experience you might have had, especially with multiple amplifiers on the list. I have not actually heard any of these. Also, if there are better options that I've missed, please mention them.

Lastly, remember that I would be buying used to maximize my options and value. Thanks in advance for any assistance in helping me choose my best path here. The help is greatly appreciated.

What I have identified as good possible options:

Parasound JC-1's

Pass X250.5

Pass XA 30.5

Jeff Rowland Model 6 Mono's -(I fear these only appear extremely rarely though, and given their age, may need servicing and new caps,etc. possibly putting them out of reach)

BAT VK-75

Modwright KWA 100SE

Primaluna Dialogue 7 Monoblocks

An old Threshold S series thats been refurbished? - These have always fascinated me, but would it last another 20 years?

Tony,

Thanks very much for your thoughts. I've done some research and it does not seem likely that any Spectral amps could be had within my budget. I have heard they are tremendous, though, but the requirements for very expensive MIT cables, by itself, would eliminate my options even if one somehow appeared at a price I could afford.

I will do further research on your Classe and McIntosh recommendations though.

"02-04-12: Tonykay
Sorry to add to your dilemna, but I would add Spectral, Classe and McIntosh to your list of possibles. Your power needs and budget will dictate the particular model. All of these companies are still in business so you should be able to have them repaired or updated if the need should arise."
John,

I greatly appreciate your thoughts on the matter. I've come very close to jumping on the Pass bandwagon, because I greatly admire what Nelson has done. I've especially targeted the 30.5's because they have tested out at 140wpc A/B. However, I have the same concerns you do.

Pass seems to have a good reputation for reliability, and if you don't have a local dealer, Mark at Reno HIFi inspires confidence; I'd expect good service. That said, if your speakers really want 100 plus watts, I'm not sure the XA-30 are what you want. I use it's cousin, the INT-30A, on 92/4 speakers, and while I think it very well suits the small acoustic music, I'm giving up grunt from the 180wpc A/AB it replaced. My hunch is that you should favor the X-250.5, even if it's less tooby, as 100 watts in the XA series is $.

Good luck!

John
Missing posts??? Ralph recommended some higher sensitivity speakers to me in a post he made in this thread on Tuesday, which I read that night. Last night, the Audiogon forums were unavailable when I checked back. Now, both that post, and at least one follow-up to it are gone. And I do not remember the speakers he was recommending.

Whats going on?
New Rogue Amp

Goldprintaudio,

I did see those amps were shown at CES and was interested in hearing what they were capable of. I greatly respect Rogue, as an American manufacturer, and especially the value they offer. I've found the character of the M180's, which I had the chance to audition, just a bit lean for my tastes, though the bass control and slam is exceptional.

What can you tell me about the new Medusa amp?

"If you are open to new, be sure and check out Rogue's new hybrid amp, Medusa. 200wpc

I just got in my first demo unit, and I am amazed at how good this amp sounds."

Again, thanks to everyone for the continuing comments and recommendations. I appreciate all of the advice and perspectives being offered.

Several people have mentioned the possibility of changing speakers and thats a fair question. I do really love the sonics of Atma-Sphere S30, and higher efficiency speakers would allow it to remain. Here is the challenge of going in that direction. The Silverline 17.5 are very good speakers, though granted, not an ideal match for the S30, as Ralph so accurately pointed out.

Replacing them will not be easy, for a number of reasons.

Martin G. DeWulf, editor and publisher of (Bound for Sound in / issue #181 / Sept 2007) said this of the 17.5's:

"Let's pretend: If someone were to ask you, "If you could have any 2-way bookshelf speaker on the market today, what would it be?" What would you say? I think my response would be the Silverline 17.5, Yes, the competition is heady, and it would include the Wilson Audio TinyTot and the Magico, amongst others. But I think I would stick with the Silverline."

One of the primary reasons I chose these speakers is the fact that they can play any kind of music very well, and I listen to acoustic music, singer songwriters, rock, female vocals, and even Gregorian Chants at times.

The small room they are in, and physically unchangeable aspects of it, also requires a bookshelf speaker, and one essentially no larger than the size of the 17.5's (14” x 9” x 15) and that are very effective in a somewhat nearfield configuration. The seating position of the listener is no more than seven feet from the speakers.

I'm not aware of any speakers of high efficiency, that are this small, which would also work optimally in the described nearfield setting, with all types of music (excepting large scale classical. That does not mean there arent any, and you may know of some.

Does a suitable replacement for these exist within the budget I have that meet my needs?

Nightfall,

"The speaker Ralph mentioned was the High Emotion Audio Bella Twin speakers"

Thank you! That was it, I knew I wasn't dreaming it happened.

Nightfall,

The speaker Ralph mentioned was the High Emotion Audio Bella Twin speakers.

Ralph, I believe you said that the S-30 would produce 45wpc with these?
"Hello Nightfall, I don't think I recommended a particular speaker, but if I did I would expect that Audiokinesis would have been on the short list. Duke is an outstanding designer and also easy to deal with."

Ralph, I've had dealing with Duke previously, and he is a great guy. Last I knew though, he did not have any speakers remotely close to bookshelf size though.
Charlie, thanks for your thoughts. I did communicate, via e-mail, with Alan previously, and his advice was that he voices the Silverlines with Pass amplification. As I noted earlier, I am a big fan of Nelson, and would be happy to go in that direction. The difficulty is that the logical, and affordable choice respective of sonic character would be the XA 30.5, and I'm afraid that simply won't produce the power the speakers need. Unfortunately, the XA 60.5 likely would but that's simply out of reach financially. An X 250, even an X 250.5 should be within the budget, but every comparison I've seen stated that these simply do not have the magic of the XA series, of which only the 30.5 is affordable within my constraints.

Hi Nightfall,

Just a quick response to your query...why not call Alan at Silverline and ask him what he would do? He's cool and will give you a straight answer. Also if I recall correctly the editor at BFS REALLY liked the monarchy 250's with the SIlverline 17.5's. Hey it's a great hobby and take some time and experiment. There really is NOT that much difference amoung most of the good amps today! It just takes some patience and DON'T listen to anyone except your own ears!

Best

I'm definitely not intending to go backwards, in terms of sound quality, from my present Atma-Sphere with this purchase. I certainly would be happy spending much less than my $4k limit, but it would have to be for an amplifier that did not represent any compromise on sound. And I'm certainly open to suggestions on anything.

If you are worried about a fixed income someday, start reducing your expenses now, starting with this amp. Consider Class D for cheap operation in the future. You can leave it on all the time. Go cheap and if you want to make changes in the future, sell it and try again. $4000 can cover a lot of experimentation and that's what this hobby is, lol! Also get something stable into almost any load, unless you promise never to buy another pair of speakers again. There are a few pro amps under $600 that run quiet that might work. Also you have a lot of boxes...you might consider reducing and assembling a simpler system...recommend balanced.
