Mid-fi tube vs high-end SS

@samureyex - still not sure why you are looking at switching to SS. If you like the sound you are getting from your tube amp but are just looking to raise the quality a bit, you could consider upgrading the decoupling capacitors. 

Your amp comes with pretty cheap CDE film caps (at least they aren't electrolytics). There are a LOT of options for caps that will likely improve (and certainly change) the sound.

I really like the copper foil caps from brands like Miflex and Jupiter, but you may not have adequate space for them - they are physically significantly larger than the CDE caps. 

A reasonably priced and sized option is the VCAP ODAM. These are very clean sounding, but are also very neutral which may or may not be what you are looking for. 

If you don't feel comfortable making this kind of modification yourself, I suspect you can find a local electronics repair shop that will do this for you at a modest cost. 

One manufacturer I can recommend is Ayre.

I own both Atmasphere and Ayre, and both sound very close to one another.-With the Ayre being a bit 'tighter' especially in the bass.

If you have been getting by with 55wpc, then an AX-7e would probably do the trick.-And, very available used.

I would also consider the Belles Aria Integrated.

@jaytor  You had some very solid points. To answer your question, the main reason I'm wanting to buy a permanent SS amp is for its convenient. Tubes are getting real expensive to maintain and I want a SS for movies and gaming for my usage as well. 

I was curious to know the kinds of improvements I can get by dropping 4 grand into a new amp. Atm I'm quite happy with the sound of my tubes on all aspects, except for dynamics, but still the dynamics are good enough.

@knotscott  I don't know much about tubes but I've put a significant amount of time into some other tubes I should buy and that tubes I've been meaning to buy is the Tesla ef806s. Thank you. 

OP. some great recommendations here. I have a Qualiton X200 and there is zero lack of dynamics in this tube integrated, however is more $$$$. 

I do have a few SS integrated in my home and as of late I have been listening a lot to my Heed Elixir a 45W SS Class A integrated and I use while working in my office. For $1395.00 with its transcap technology it it sounds very tubey for a SS IA. I could live with this little thing, and it has an outstanding headphone section (better than the X200) and a MM Phone Pre (Heed Quasar). Built like a tank.
