Can tube amps give true high end bass?

Newbee, have you looked at the Atma-Sphere amps? You're comment:

"I'm still looking for a tube or ss amp which has the best of both designs, that has warm, full, tight low frequencies with natural mids and highs allowing for great detail with no thinning or brightness."

is exactly what I found in the Atma-Sphere MA1's. I was completely stunned by the bass articulation they provided to my Magnepan MG3.6r's, a speaker that most say can NOT be driven by a medium powered tube amp, much less an OTL. It truly was a revelation! The mids were gorgeous and the highs as airy as I've ever heard...really made me appreciate the Maggy ribbon tweeter, something I wasn't fully able to do when they were powered by my Parasound JC1 monoblocks.

Ulf, I do think good tube amps can provide better bass. Six or seven years ago I used Manley Neo Classic 250 tube amps with Avalon Eclipse speakers and I found the bass more natural than with my previous Levinson SS amp.

I spent several years living in Soulard (St. Louis area) and listened to live music at least 4 times per week. The Atma-Sphere's, and to a lesser extent the Manley's driving the Eclipse, provided a much more realistic upright bass. The way an upright bass projects out into the room is not a start/stop affair...it's hard for me to describe it...maybe "expansive". You get the initial transient followed by this ballooning of the fundamental and it's harmonics. Oh heck...my language is horrible...wish I could describe it better.

Good luck!

Perhaps the Ayre V1xe and Krell 450mcx monos just aren't up to the task? Even the Krells' 450 transistor watts may be no match for a 40 Watt tube. Perhaps the Ayre's zero feedback design is a false start without the right kind of harmonics?

Thanks all for your imput. I learned a bit more!!
The old "fact" that you need big transistor amp to get solid deep bass seems gone.My Silverline speakers seems to love tubes, especially in the low bass!

My McIntosh c220 (tube)/ Ayre V1xe are really good but that "prototype" tube amp (integrated 2x40W)has left me no rest and I have know asked the constructor to build a full finished amp.I report back when it is in my system.

mine does, bass galore, KT90 tube. Also 6550 tube.

"Best of the both worlds"...

Seems really hard,if not impossible to get.I don't know if i will achieve it,but it is my aim in my forthcoming "ultimate" system.It aimes to be the best system i have seen or heard of this far.

It will also be based on SILVERLINE speakers.Only different model.SINFONIA.
I believe that you know this model because you also own a similar high-end product from the same company.
I don't know about Grande La folia,but Sinfonia is tri-wired.This means i can connect 3 types of amps.
One connection is only for the rear-firing 12" woofer,one for tweeter and 2" midrange,and one for 7" mid and 12" front woofer.So i can play with different amps.

I chose to go with custom-made amps,made by Trlin Audio.I know the constructor personally,he lives in my city,and is very knowledgeable,especially on tube-related subjects.More than 15 years of experience in that field.He recommended 6 320B XLS SET monos,high-end,made with only the best possible parts.I chose to go with 4 of these monos - 2 per speaker.

But i plan to use transistor amplification on rear 12" woofer.I think that bi-polar transistor in AB class will give the best bass.Most precise and tight as you can get.Fastest recovery time after each peak.And i love it that way.Trlin Audio also makes those,but i will limit mine to 18 Watts exactly (same strength as 320B XLS monos).

This is the best i have come up with this far.I plan to close the bass reflex port of the front 12"woofer,to gain a bit more speed and accuracy,for it will be connected to 320B XLS monoblock.
Rear woofer will give the depth,which i personally enjoy very much.I guess this will be fine,if done properly.

I think this will be "the best of the both worlds".But only testing and testing and testing will give the true answer.I will post about the results of these tests,and also about the quality of Trlin Audio's Monos.Can't wait.But I have to wait for 3-5 months for all this to happen,as the apartment for my gear is being built.

Any thoughts or advices?Much welcomed.
