Review: Apex Pinnacle Headphone Amplifier and Stereo Preamplifier - Page 2

post #16 of 55

i believe the 307A was around 6K and this beast is now at 10K. quite a bit of jump, in my opinion. wish they would make a different version of the Pinnacle with fewer input/functions with a lower price. :(

I may get to test this thing against my SDS-XLR when I get the latter fixed. Todd has offered to let me audition it for a week, and I'm hoping it will be just as good/better so I can free myself from worrying about SinglePower's reliability.

Just got my copy of the Absolute Sound and read the review of the Pinnacle. OUTSTANDING!  Well done Pete and Todd!

The Pinnacle is a brilliant headphone amp and preamp. It combines resolution and a gorgeous tonal texture and silkyness without a hint of harshness or grain or any analytical sound.

I just lean into the sound as it reaches deep into the characteristics of each musical element, including vocals which are so hard to get right.

Whatever audiophile adjective I can come up with, the Pinnacle achieves just the right balance, without a false note anywhere.

Some more thought on the Pinnacle after enlisting it as a preamp:

 

After experience with good preamps from Mcintosh, Rowland, VanAlstine, EMM, Threshold, Placette, and Levinson (a No. 32 some years ago), the Pinnacle is a revelation, with
a tonality that is fleshed out so nicely with great expression and character, where the character of each musical element is very unique, and some sort of rounded, 3D shaping of images that is riveting.
And with all this goodness, there is zero listening fatigue. I didn't believe a preamp could do so much.
And all of this is just with regular redbook CD, and old cheap ordinary CDs of music from the 50s to now for that matter.

By the way, I use a Brimar 6NS7 GTY NOS tube in the Pinnacle.

One nice thing about the Pinnacle is that you tube roll with just one tube, the 6NS7.

Well ... I wish, but not quite.  I've found it worth trying each different 6SN7 with first the Sophia PX4s, and then the KRs.  Usually the Sophias are better, but sometimes the KRs add something.  My KRs are very microphonic though, so I wouldn't use them for preamp duty.

I didn't know there were any alternatives to the supplied PX4s. Maybe I missed something around here. Thanks.

(Not that I'd feel any to do so at this point, but I'd just like to know).

(I noticed in your review Innerspace you used the supplied ones (the Princesses), even though you mentioned the KRs.)

for 10000 it looks ugly...

post #27 of 55

It is a bit of a Frankenstein-looking beast, but not as much as the big Woo setups, and it runs pretty cool for tubes, and that's more important I think.

And of course, its beauty is in the ear of the beholder...

no wood work for 10000 ? that's lame.
