I was impatient and it's 3am so I wasn't able to assemble the box quietly (hammers aren't known for being quiet, yeah?), so I used a copious amount of masking tape to temporarily hold it together while testing.

 

Mids are definitely lush.  Reminds me of my HD595 + LD II++ pair I had.  Only with better bottom end and better soundstage.

 

At first, I felt I lost some sparkle on the top end, but then again, the HD650's aren't known for being sparkly.  I stopped thinking about that, and concentrated on the mids.  The delicious smooth and warm mids.  Man.  Good stuff.

 

So far, I'm impressed.  Have a lot more listening to do though!  I don't think I'll be selling my Lyr through.  It's still a great amp and I'm sure I'll regret selling it if I ever get an Ortho or something to drive.

 

Will return with pics and impressions once I get more listening time.


See if you can find yourself a nice 1950's 12au7 Tung-sol JTL they are a little more expensive than the RCA 12au7 clear top but are more refined and resolving whilst still retaining that treble sparkle that the cleartops have that works well when in combination with the HD650.

Have you tried the Amperex Bugle Boy 12AU7 ? I found it even better than the TS 12AU7.

Yes I have but preferred the early 1950's Tung-sol JTL &TS Black glass to it. However it was in my early days of rolling and I expect it might have been one of the very many latter Bugle boy versions & not the early 7316 flasher one which is meant to be the premium version that most of the reviews look to be based on.

 

The later Tung-sol 12au7 also don't seam to be as nice sounding as their earlier tubes. Once I switched from the HD650 to the T1's I found the Mullards and E80cc's more to my liking mainly because the T1's didn't benefit from the brighter sounding tubes like the HD650's did.

 

Its quiet surprising how different combinations work together or don't as the case may be. I have one TS5998 that is particular about which brand of e80cc its paired with yet works fine with all other E80cc & 12au7 variants etc.

Enough and then some, my stash has been slowly growing and I have been letting a few go to fund some other related purchases :atsmile:

Of course normally this would mean blowing out your ears, but that's why you use a passive preamp to control the volume instead.
It's a trick I picked up with my last tube amp that had channel imbalance at low levels. ATM my Crack SB is set to max volume and my passive preamp to around -40db. 

The sound difference is quite extreme. Highs are much more crisp and beats more punchy. All in all the sound is much, much more dynamic. It's like going from a 50$ DAC to a 500$ DAC IMHO.

Why havn't I seen anyone mention this? Is there something I don't know? Does it hurt your tubes to play at max volume all the time? What's the catch? :confused_face_2:
 

At maximum volume, the level control functions as a pair of 100K resistors at the input. This isn't an operational problem unless you don't have a different way of controlling the signal coming in.

I would love to and have no doubt their dac is going to sound wonderful however personally its to much for me to spend on product which I am electively buying unseen, unheard, requires some assembly and which falls in a category of product type which historically becomes obsolete rather swiftly.  Its also at a price level which if you don't mind if buying used its possible to find some very highly regarded options.

 

I am looking forward to hearing some reviews if its as good as we hear then it will be around for a long time.

how is the bottlehead for hd800? and can i buy it complete? without building it?

post #5023 of 6337
1. The Crack is a great budget option for the HD800s. Some would call it a giant slayer.
2. Where do you live? Bottlehead can put you on to a builder they use or, alternatively, there are many on this forum who would be happy to build one for you at a reasonable cost.

The impressions that I've read of the hd800 and crack are quite good. I'm even considering the pairing myself. ;) 

 

I'm still looking for a TS 5998 or comparable if anyone is selling.

I'm using the HD800 with my Crack, though the sound is pretty good, I MUCH prefer the T1 with the Crack. When I heard the T1 driven by the Crack then switched over to the HD800, I immediately felt kind of lush and it lacks of transparency as well as the clarity of the T1.

 

I think you should seriously consider the T1 for the Crack as well.
